How to Plant up an area with grown cover shrubs

Hydrangea macrophylla 'Merveille Sanguine'

The secret to making a low maintenance garden border is to start off with no perennial weeds, after that the maintenance is no worse than a lawn in the first couple of years and far less thereafter. When creating a border most people make the mistake of making it too narrow, a 300mm (1 foot) deep border will just not work. If that’s all you can manage your better off with climbers or wall shrubs. 1.5 to 2 metres (5ft to 6ft 6inches) is the sort of depth you should be aiming for, not all gardens may be able to accommodate this but the closer you can stretch to this the better. In a very small garden you may do better having one deep border at the bottom of the garden and climbers and wall shrubs on the other walls.

Once you’ve chosen your area you need to remove any perennial weeds before you start to plant. Removing them once the plants are in and growing is far harder and the reason many peoples’ borders fail to work. Weeds like couch (Elymus repens ), ground elder (Aegopodium podagraria) and stinging nettles (Urtica dioica) have a spreading root which can quickly grows through the root ball of newly planted shrubs making the weeds extremely difficult and sometimes impossible to get rid of. Where the area is an established lawn these weeds will have not been able to become established because of the regular mowing. Here the grass can be stripped off but some weeds will be left behind such as dandelions (Taraxacum species) with their deep tap-root. The most reliable way is to kill off all the vegetation with a glyphosate weed killer (sold as Roundup, Gallup and other brand names). Leave the weeds to die down, this

can take a week or two and then turn the ground over with a garden fork, removing any roots and large stones. If the border is edged by a lawn, tidy up the edge to form a clean line and spread 25 to 50 mm (1 or 2 inches) of organic matter and use a garden fork to combine it into the soil. If the soil is very sticky with clay, mix some sharp grit (about 1 to 4mm) to open the soil up making it better draining, easier to work and with more air in it.

The source of the organic matter is not important so long as it’s free from contamination and weeds, your choice can be bases on price and availability. Well-rotted garden compost is ideal but few gardens have a large supply of it, peat was the traditional alternative and although it is a good soil improver these days its environmental cost makes it undesirable. Many councils now sell recycled waste as compost and these are normally well made, just don’t pay a premium for an “organic” label it does make the compost any better; just allows the seller to claim a higher price! If you live in a rural area you may be able to get farm yard manure and if rotted down this is very good, but in practice farms don’t want to leave the manure heaped up for a year or two to rot down so if you are going to use it you may have to except you must leave it to rot down before you can use it or the rotting straw can soak up any available nitrogen.

You are now ready to plant the border. Choose shrubs which have a good dense canopy of leaves in summer so they smother any weeds before they can become established. Being evergreen is not important in this context as weeds germinate doing spring and summer, but some will provide some interest during the winter. Try not to focus on what’s in flower at the time as you want as long a period of interest as possible and bear in mind foliage lasts a lot longer than flowers. When walking around the nursery or garden centre make use of the labels and staff, if they’re not helpful go somewhere else! A good supplier will take pride in their stock and gave a good knowledge of it. Deciding how far apart the plants should be is tricky and it can be very difficult to visualise how big a plant will be in a few years’ time. The tendency is to over plant, especially in small areas so have a look at the label and ask if in doubt. Also bear in mind a 1.8 metre (6 foot) high plant is generally going to end up as wide as it is high.

Once you made your choice and paid for them pack them in your car carefully, DO NOT have them sticking out of sunroofs and windows, they will travel perfectly well laid on their sides; even if some end up gently laid on top of one another. When home get them out of the car as soon as possible, stand them in a sheltered corner and water them well. Like this, so long as they are keep watered they will be fine for up to a week if you run out of time.

Planting can be done on any frost free dry day and start by setting out your plants in their intended positions. Now is the time to make any last-minute adjustments to the arrangement before planting.

To plant use a garden spade to dig a hole larger than the plant pot, remove the pot, place the plant in the hole and firm the soil back around the root ball with your heel, making sure the top of the compost is level with the border soil. To remove the pot grasp the plant where it emerges from the compost and give the rim of the pot a firm tap with the palm of the hand. After all the plants are in rake over the surface to tidy up and water the plants really well, in part to settle the soil in around the root ball.

Give the borders a quick check over once a week for any weeds emerging, and remove them; most weeks there will be nothing to do and the next spring feed them with a general fertilizer.

Cornus controversa

Cornus controversa 'Variegata'
Cornus controversa ‘Variegata’

Best known in gardens in the form of Cornus controversa ‘Variegata’ this plant has had a convoluted history. The species C. controversa Heml. was first “discovered” in cultivation. In January of 1909 an article was published in Curtis’s Botanical Magazine which discussed the naming of Cornus macrophylla and the authors noted that there appeared to be confusion regarding the name. Though introduced back in 1827 it was not widely grown but it was known to be a tall and bushy plant when observed in the wild and this varied little over it wide natural range.  William Botting Hemley who had retired as Keeper of the Herbarium and Library at Kew the year before had studied this and noted that the examples in cultivation were a mixture of two species: one with opposite leaves and the other alternate.

The simple fact was that the naming had got into a mess but when the original specimen that Wallich had named C. macrophylla was checked it had opposite leaves and the original description in Flora indica of 1820 described the leaves as “sub-opposite”. Next Meyer in 1845 had also described the plant in a Saint Petersburg publication but naming it C. brachypoda. All this resulted in America and continental Europe using Meyer’s name of C. brachypoda for the form of the plant with opposite leaves and C. macrophylla for the alternate leafed form while in Britain both forms were known as C. macrophylla. In an attempt to clear things up the German botanist Bernhard Koehne tried to split the species in the belief that the Himalayan form was a distinct species which he called C. corynostylis but got confused between the opposite and alternate leaf arrangements. To clear up this confusion William Hemley proposed that if the plant had its leaves arranged opposite one another on the branches it should be called C. macrophylla Wall. as has been Nathaniel Wallich’s intention and the alternate leafed form should be a separate species Cornus controversa Hemsl. meaning cornus controversial, a most appropriate name. And that is as it has remained; apart from an attempt to place several of the cornus species, this one included, in the genus Swida in the 1960’s.

That would be the end of it with C. controversa Hemsl. providing us with a very garden worthy small tree with tiered branches and masses of cream flowers in May, but towards the end of the 19th century a variegated from was found and shortly before 1890 Veitch Nurseries introduced it as Cornus brachypoda ‘Variegata’. Now known as Cornus controversa ‘Variegata’ this is a plant which stands out to gardeners and non-gardeners alike. Smaller growing than the original but retaining the tier arrangement of branches, the leaves are longer and narrower and tend to be asymmetrical in shape with an irregular creamy-white margin. Known by the common name The Wedding Cake Tree its hardy in the UK and was awarded an AMG by the RHS in 1993.

Its size and shape means it is best suited to a larger garden where it has room to grow and show off its tiered habit and would look particularly effective in a large border with an under planting of spring bulbs. The flowers are followed by berries and on some soils attractive autumn foliage. The plant is often produced by grafting and so care should be taken to watch out for suckers from the more vigorous rootstock which need to be removed as soon as seen.

Viscum album

Viscum album
Viscum album subsp. platyspermum on limes trees at Hampton Court Palace, London

Mistletoe has fascinated humans for millennium, many plants have superstitions attached to them but mistletoe seems to have attracted more than most. It’s not hard to understand that a clump of evergreen leaves growing out of dormant tree in midwinter would grab the imagination. The druids are said to particularly venerate mistletoe growing on an oak tree, something it rarely does, harvesting it with a golden scythe on the 6th day after a new moon. Consisting that the plant is woody and gold is an extremely soft metal I not sure how true that is and as they left no written records of themselves this could just be dramatic invention. It still plays an important part in culture with the tradition of kissing under the mistletoe at Christmas but the plant is poisonous with a few berries bring on stomach ache though serious poisoning is rare.

Viscum album is wide spread across Europe and it has over the centuries been seen as a cure of a vast range of ailments right up to the present time. Diokorides (the 1st century AD Greek physician) reported that Hippocrates (in the 4th to 5th century BC) believed mistletoe could be used in the treatment of complaints the spleen and menstruation. Over the following centuries it has been recommended as a treatment for swellings, tumours, epilepsy, infertility and ulcers. In more recent times people have tried to use is to treat hypertension and cancer.

Viscum album
Viscum album (Mistletoe)

The genus Viscum L. contains about 100 spices but only V. album L. is native the UK and then mainly in the south and midlands. In naming Viscum album L.. Linnaeus took the Latin for mistletoe as the genus and album, no doubt referring to the distinct white berries, for the species name and listed it in volume 2 of his Species Plantarum. The genus Viscum L. is presently in the family Santalaceae along with 6 other genera. The common name Mistletoe comes from the old English mistel and many semi-parasitic plants around the world have the same common name. It is also known as including All-heal and Masslin in England and has many other names across Europe, Germany having a particularly large collection of names for it.

Mistletoe is notoriously difficult to establish and the species is now divided into 3 sub-species depending on the host plant it lives on.

Viscum album subsp. abietis (Wiesb.) Abrom. which grows on Abies species.

Viscum album subsp. austriacum (Wiesb.) Vollm. which grows on pine trees and very rarely on spruce.

Viscum album subsp. platyspermum Kell. (subsp. album) which grows on hard wood trees.

This goes in part towards explaining why it is so difficult to establish mistletoe as the sub-species are very specific to their chosen host but there also appears to be genetic factors as not all potential host can be infected with equal ease. For example, oak is rarely infected but even then there is a wide range of how readily a plant will be infected with a particular oak species. Therefore, where a plant has only a few mistletoe plants on it not become host to a lot and only specimens with a lot of mistletoes will host a lot.

Mistletoe is evergreen with tiny flowers that are insect pollinated and would never be noticed; the insects are attracted by the sweet smell . The male and female flowers are on separate plants with about 4 times as many female plants as male ones. The plants flower between the end of February and April  and the fruits (or berries) appear from October to May with Mid-March to mid-May being the best time to sow the seed, making sure to brake the outer coating and allowing the sticky contents to help the seed adhere to the bark of the host tree.

Mistletoe is a parasite, all be it a partial one, taking water and minerals from the host tree and this weakens the tree. Infected apples trees will yield between 7% and 56% less depending on how vigorous the rootstock is, with the plants growing on the more vigorous rootstocks affected the least. Once established the Mistletoe shoot doesn’t divide for the first 3 or 4 years then each year the shoot divides in two, ultimately reaching about 1 metre across, so giving a very rough and ready guide to its age.

 

Prunus laurocerasus

The cherry laurel is one of the most widely planted screening plants in gardens having reached western Europe by the end of the 16th century and is recorded in cultivation in Britain in the 17th century. It has been cultivated that extensively its geographical origins seem to be a little hazy but would appear to stretch from the east coast of the Adriatic sea eastwards along the south coast of the Black seas as far as the Caspian sea.

It is hard now to appreciate the effect that this plants arrival would have had in western gardens at the time of its arrival. Gardens at the time would have had very few evergreen bushes and along comes this large vigorous bush with its mass of large smooth shiny evergreen leaves. Added to this is the masses of white flower spikes in late spring and the small black fruits in autumn. Few plants offer such a range of attractive features. Sadly now it has been relegated to being a plant of little garden value.

This is in part because we have so many more plants to choose from now but also it has been a victim of its own success. It has been over planted in the past because of its appeal as a fast growing evergreen leading it to being used where a fast evergreen hedge is wanted’ a role it isn’t really suited to. Its large leaves look tatty and unattractive when it is cut with shears or a hedge cutter and it should really be cut back with secateurs. If you must have an inappropriately fast growing hedge you are better with × Cupressocyparis leylandii. On the rare occasions it is allowed to grow unmolested it makes a fine large flowering shrub in a large garden. Unfortunately it most often ends up crammed into far too small a space with its hacked leaves blacked at the cut edges. I have seen examples of people trying to grow it as a 600 mm high by 300mm wide hedge, something such a large and large leaved plant will never do successfully and which there are far more appropriate plants for.

Prunus laurocerasus 'Castlewellan'
Prunus laurocerasus ‘Castlewellan’

In most cases the form Prunus laurocerasus ‘Rotundifolia’ is grown in place of Prunus laurocerasus having leaves half as broad as long and a yellower green than the species. Other cultivars of note are Prunus laurocerasus ‘Castlewellan’ (syn. P. ‘Marble White’) a less vigorous plant with white marbled leaves, Prunus laurocerasus ‘Otto Luyken’ )a low shrub with upward pointing leaves and stems and Prunus laurocerasus ‘Zabeliana’ a low horizontally branching shrub which makes excellent ground cover even under the dripping shade of trees.

Prunus laurocerasus fruit
Prunus laurocerasus fruit

Along the way it acquired a variety of names until Linneaus set it as Prunus laurocerasus L. in the 1753 in the first volume of Species Plantarum. Prunus is the Latin for a plum tree which is in the genus and laurocerasus comes from laurel, the Latin for laurel, and cerasus, the Latin for cherry. This and the common name reflect the small round black fruits which resemble cherries. These cherry like fruits or their common name of cherry laurel should not lead you to believe the plant is in any way edible. All of the plant is poisonous and the reason you do not hear of people being poisoned by it is because you will be very ill before you have chance to eat sufficient to poison yourself. These poisonous chemicals are also the ones which produce the almond smell from the crushed leaves. That said this has not stopped people from trying to use it as a quack medicine. Laurel water was used for various treatments but is basically a solution of hydrogen cyanide of varying concentration and so extremely dangerous.

Actinidia kolomikta

This beautiful wall shrub deserves to be far more widely grown yet currently only about 53 suppliers are listed in the RHS plant finder. This is surprising as few other wall grown plants provide such an attractive display for so long. The foliage opens green but quickly develops a white and pink variegation as if they had been dipped in pots of white and pink paint. This variegation only develops in the presence of plenty of sunlight and along with the shrubs scrambling habit means it is always seen grown against a south facing wall, although I can imagine it would also be very attractive scrambling over a south facing bank.

It’s white, slightly fragrant, summer flowers are over shadowed by the foliage and as it is both dioecious and it is only the male plant which appears to be in cultivation you are unlikely to see the fruits which are said to be edible. The closely related A. deliciosa (A.Chev.) C.F.Liang & A.R.Ferguson which is better known as the kiwi Fruit and several of the 100+ species of Actinidia Lindl. are cultivated commercially for their fruit.

Actinidia kolomikta (Rupr. & Maxim.) Maxim. is easy to grow not being particularly fussy as to soil type and vigorous, reaching up to 4.5 to 6 metres up a wall. They are reasonable easy to propagate by cuttings or layering and are perfectly hardy.

First described by Carl Johann Maximowicz and Franz Josef Ruprecht two botanist working in Saint Petersburg in the 19th century; they initially placed the plant in the genus Prunus but subsequently both revised their decision and Maximowicz placed it in the genus Actinidia created by the British botanist John Lindley which he named after the Greek for ray because of the styles in the flowers. The plant is native to the region of Amur in Russia where it is known as kolomikta and Maximowicz described the plant growing wild in his 1859 book Primitiae Florae Amurensis (Beginnings of an Amor Flora). Amur Oblast is still a largely remote region with temperatures that can range from above 30°C in summer to below -40°C in winter.

How to cut back over grown shrubs

Before reaching for the pruning tools you need a clear idea of what you are hoping to achieve and in the context of this post it is a healthy plant which fits, both physically and aesthetically into its location in the garden. When you have finished you want something which does not overwhelm the area around it or look unattractive to the eye.

Pruning is not the easiest of things to teach, partly because of the different requirements of different plants but equally because it is as much art as science. To start with a few preliminaries:

  • Plants don’t always respond well to pruning – not all plants will come again if you cut into old wood, this includes nearly all the conifers but also a number of others.
  • Those that do, don’t always do as you expect – often a plant will respond to pruning by producing a mass of soft shoots rather than one or two useful ones.
  • Once you’ve cut it off you can’t put it back – so if in doubt delay cutting and then take off a bit at a time to see how it looks
  • Think ahead to prevent accidents – you would be amazed at the number of people who actually cut off the branch they are sitting on!
  • Make sure you are suitably equipped – as you will never make a tidy job using poor/blunt tools.
  • Plan first, act second – have a really good look at what you’re tackling and how your cuts are going to affect the plant before you do anything.

The first step is to remove any dead and diseased material, the second remove crossing branches and the final one is to shape the plant.

Any dead or diseased parts of the plant are going to be no benefit to you or the plant and if not yet diseased it probably soon will be. Yes that branch may be in just the right place for what you wanted but if it not healthy it’s never going to look right and will end up causing problems further along the line so cut it back to healthy growth just above a bud or close to where it branched off a larger part. If it’s a larger branch do it in three stages to prevent it damaging the rest of the plant when it breaks away from the plant. Work methodically, starting with the larger branches so that any damage caused by removing them can be cleared up as you go.Branch pruning

Once we’re left with a collection of healthy branches we can turn our attention to any which are crossing through the bush. This is not a hard and fast rule as the first but  there are reasons for it. First such branches almost always end up rubbing against one another as the plant moves in the wind. This causes the bark to be worn away at these points and it is the bark which acts as the plant’s main defence against diseases getting in. This means that sooner or later these places will be where problems are going to occur. The second reason is that plant diseases tend to benefit from a still moist atmosphere and this is more likely to occur in a tangle of branches than a nice open structure which the air can move  through freely. Finally it tends to be more visually pleasing not to have a lot of branches crossing through.

Now we can come to shaping the plant and this is much more a matter of personal taste.There are though a few things to consider. If by nature it’s a big plant and you are going to cut it down a long way , then it will quickly re-grow and you will soon need to repeat the process. Should you allow it more room or is it simply not in a suitable place? If you are trying to lower the height of the plant, remove the tallest branches completely low down where they divide and allow the shorter branches which are left to form the new top. Nothing looks worse than just choosing a height and cutting everything off in a level line at this height, but you regularly see this done and often by people claiming to be professional. Once done the plant is very unlikely ever to recover aesthetically.

The important thing is to take your time and regularly step back to get an overall view of the job as you go. Whatever plan you start with you will have to fine tune it as you go as the job progresses and new ideas occur.

Buddleja davidii

Buddleja davidii 'Burgundy'
Buddleja davidii ‘Burgundy’

Buddleja davidii Franch.is a popular garden shrub which has escaped cultivation to become established as a naturalised plant in the wild, where it can often be found on waste ground around towns and cities. It will grow happily in most garden soils and can even be seen growing out of cracks in masonry on buildings. It does prefer a sunny position as none of the buddlejas do well in shade. It grows well in even poor soil sending up long arching branches which are topped by the flowers in ranged in a cyme in late summer. Being a late flowering shrub it responds to early spring pruning and when pruned hard in March it produces far more flowers. These flowers give it its common name of butterfly bush as there strong scent is irresistible to butterflies.

Buddleja x weyeriana 'Honeycomb'
Buddleja x weyeriana ‘Honeycomb’

Its ease of cultivation and natural variability has lead to a host of named varieties being selected and introduced varying from white through to purples and very dark blues. The RHS plant finder currently lists 121 different ones, including some which are forms of Buddleja x weyeriana – a hybrid between B. davidii and B. globosa.

The genus Buddleja L. was named by Carl Linnaeus in ‘Species Plantarum’, naming it after the Reverend Adam Buddle but of reasons unknown he spelt it with a “j” when strictly speaking it should be spelt with an “i”. This has lead to considerable confusion over the

years but as he repeatedly spelt it this way that is how it should be spelt. The only Buddleja known to Linnaeus was B. Americana L.which William Houstoun had sent back to Europe from the Americas and even then the spelling was causing confusion as in one of his illustrations he spelt it incorrectly both times even though he attributes the naming to Linnaeus. The species B. davidii itself was first sent back to Europe from China by the French Catholic missionary Armand David having found it in  August of 1869 and  Adrien René Franchet working in the herbarium of the natural history museum in Paris published a description of it in 1887 naming it in after the discoverer.

Fatsia japonica

Fatsia japonica
Fatsia japonica

One of the classic garden plants for shade Fatsia japonica is much admired for its large, glossy, evergreen leaves and easy temperament. It grows happily in any reasonable garden soil and does particularly well in shade, though not so well in dry shade. It is also tolerant of a maritime garden though its large leaves will need some shelter from strong winds. The large fleshy leaves evoke the image of lush tropical rain forests but the plant is reliably hardy, though the result of crossing it with ivy produces the less hardy x Fatshedera lizei. Quickly forming a medium sized shrub with flowers borne on the end of the shoots. The flower buds and white flowers look a lot like a scaled up version of Ivy flowers, appearing in autumn. This late flowering means though the buds are reliably formed in the UK the flowers are often damaged by frost.

Fatsia japonica leaf

Known by a variety of common names including Japanese aralia, castor oil plant, fatsi, fig-leaf palm and glossy-leaved paper plant; F. japonica was originally described by Carl Peter Thunberg in 1780. This followed his trip to Japan where it grows wild and he named it Aralia japonica. It was re-named in 1854 by Joseph Decaisne and Jules Émile Planchon, two botanists working in France. They took it out of they genus Aralia and created the new genus Fatsia for it; so the name is now Fatsia japonica (Thunb.) Decne. & Planch.

In the wild Fatsia japonica is found from central Japan south along the Japanese islands almost to Taiwan and in South Korea. It is sometimes described as a monotypic genus, meaning that there is only one species init, but in fact there is at least two other species of Fatsia, Fatsia oligocarpella Koidz. and Fatsia polycarpa Hayata.

It was introduced to western horticulture in 1838 and though the plain green Fatsia japonicais the one most often seen in gardens others are available and the variegated form Fatsia japonica ‘Variegata’ which has splashes of white on the leaves is worth looking out for.

 

Hydrangea aspera

The rough leaved Hydrangea is one of the less commonly grown examples of this important genus in our gardens, but makes an excellent addition to the garden. The large velvety leaves provide an attractive display all summer covering this medium sized bush. And come June and July this is topped with dark lilac “lacecap” flowers. As is typical of Hydrangeas Hydrangea aspera D.Don is easily grown and need a shady location, making it ideal in front of a north facing wall or fence, or in the shade from trees. It is a very variable species and some people have questioned its hardiness but I have seen it grown successfully all over the UK. That said it probably benefits from some protection, particularly from strong winds which would damage the leaves, though this protection could easily be provided by the fences around most gardens or by a woodland aspect.

An oriental species it is found growing wild in the Himalayas, West and central China,Taiwan and Myanmar (Burma). It was first described by the Scottish botanist David Don in his 1825 flora of Nepal, placing it in Linnaeus’s genus Hydrangea L. In gardens it is often represented by Hydrangea aspera D.Don ‘Macrophylla’ a sterile selection with large leaves and flowers.

The variability of Hydrangea aspera D.Don, probably due in part to its wide geographical distribution, has lead to a degree of confusion regarding the different subspecies, cultivars, etc. The RHS database lists about 38 different entries under Hydrangea aspera D.Don including several subspecies. I it is doubtful how many of these are valid as the International Plant Names Index (IPNI) does not recognise any valid subspecies of H. aspera,raising them to the level of species.

The Concise British Flora in Colour by W. Keble Martin

William Keble Martin was an amateur botanist in the must noble tradition of amateurs. That is to say he was not employed as one but was every bit as skilled and dedicated as any “professional” botanists. He was formally trained as a botanist but instead of following this path chose to be ordained and spent his entire working life working as a parish priest.

Throughout his life though he maintained his keen interest in botany and over a period of over sixty years studied and drew over 1400 native British plants in exquisite detail. It was not until he was 88 years old was this collection first published. These days the work of botanical illustrators is over looked, having been pushed aside by the ease, speed and ultimately cost of photography. The draw back of this is that a photograph can only ever be one example of a plant on a particular occasion, but plants are far more viable than this. The blunt tool of the camera can never isolate and capture the spirit or soul of a plant in the way a skilled artist can. Therefore the simple skilled illustrations in this book gives the reader a far clearer understanding of what a plant actually looks like than a “modern” glossy book ever can. I don’t know what lead Rev. Martin t to paint all these plants but I very much doubt anyone will try to repeat his work partly because he has already done it and partly because as he working away, colour photography was evolving from a laboratory experiment into mainstream use.

What he left us was though a remarkable tool for identifying British plants. Some of the names have moved on but still the modern alternative can readily be found by cross referencing with new publications. Sadly this book is no longer in print but can be found ridiculously cheap on the second-hand book market. . In a perfect world a publisher would take these illustrations and re-publisher them with up-to-date names but I don’t imagine the economics of the book world would make this a practical proposition.
