Growing Hostas in Your Garden, They Can be a Great Addition to Any Garden

TRANNIE 1 Cut out?- Hosta fortune  is a long time familiar species unknown in the wild) ... The Hosta, once referred to as the Funkia, commonly called the Plantain Lily is a truly oriental plant in origin. Japan is the host to most of the 20 species, which can be found virtually everywhere, showing their amazing adaptability to grow anywhere from damp woodland shade in rich soil, or in open in boggy sites in snow-melt meadows, or growing in shale clinging to mist-cloaked mountainsides.

Their ability to grow in virtually any climate zone in the United States, from Southern Georgia to Anchorage in Alaska, has made them the most popular plants by far in the United States. They fit in with the American style of gardening in the large open plan style of the suburbs. Here hostas come into their own as maintenance free groundcover around the base of shrubs and trees.

Hostas as groundcover under trees and shrubs

To the British gardeners eyes they may seem garish, but the hosta bug bites hard in the U.S, and if it is followed by the urge to collect as many different sorts as possible, whether they are just different species or the incredible number of varieties (the numbers seem ceaseless), that is when hostas can get tiresome; in collections of huge swathes of plants with no dramatic relief in height or leaf shape.

However, if you want a ground cover plant to add colour or light to dappled woodland shade, or you need some reliable edging plant to create a margin between pool and bog garden, or to display some permanent interesting foliage through the drab times in the perennial border, hostas have got to be included in the very small contingent of really suitable and useful plants./(TRANNIE 4 Maidenhair Spleenwort and Hosta sieboldiana working together in shade that few other plants could tolerate)/ / (TRANNIE 5 Hosta sieboldiana Elegans helps visually hold an informal planting scheme together on a pool edge)/ / (TRANNIE 6 The species plant H. crispula brightens up the shade in a leafy perennial border in late summer)/

Being A Good Sport

Hostas are easy to grow in the right conditions but it is impossible to grow them from seed true-to-type, and so they have to be propagated by division. But if you had a mind for creating a name for yourself in horticulture the possibility of breeding a new variety of hosta with your name on it is waiting on your threshold.

All the species and new varieties are excessively promiscuous and it is difficult to avoid them crossing with one another. It was in the United States that most of the innumerable varieties have been bred, some of them bearing the names of their breeders like the golden edged sport of Hosta sieboldiana Elegans, Hosta Frances Williams by Mrs Frances Williams in the 1930s. In the last 25 years, Gus Krossa has produced the classical upright giant H. Krossa Regal.

In 1965 Hosta Royal Standard was the first hosta to be patented by John Grullemans. Although most hostas are appreciated for their foliage this was one that had exquisite fragrant white flowers. You can always spot one of hybridizer Tony Avents plants, not because of his name ascribed to the plants but the nutty names he gives them, like H. Elvis Lives, Elephant Burgers, White Wall Tire,Red Neck Heaven, Waving Wuffles and what he describes as the ugliest hosta ever bred, a spotty one called Outhouse Delight ./(Hosta Elvis Lives in amongst some of the more popular American hybrids at the Tatton Park flower show this year.)/

Paul Aden, who was one of the founders of the American Hosta Society, was keen to exploit the advantages of tissue culture in its early days in order to get his introductions propagated as rapidly as possible in large quantities. Regarded by many as the doyen of hosta hybridisers, he has introduced such popular varieties as the large leafed H. Sum and Substance and the blues H. Blue Angel and Love Pat.

Low Esteen In The UK

  • The Americans cannot understand it. They regard the UK as having the perfect climate for growing hostas and we dont seem to like them. Here they grow bigger, and in varieties like H. Halcyon, the flowers are more colourful and stay in bloom for longer.

  • It is cool enough to preserve the waxy glaucous bloom on the likes of H. sieboldiana Elegans, but the yellow varieties have a tendency to look sick rather than coloured. Giving Hostas with yellow in them less of the shade and plenty of sun, particularly in the afternoon, will burnish up the hues a bit.

  • However the quandary comes with varieties that have yellow and green in them like H. On Stage. The advice is to experiment with position to see what brings out the best colour by growing them in containers before you commit them to a position. /(TRANNIE 11 H. Halcyon)/ /(TRANNIE 12 H. Some and Substance, Aurea with H. So Sweet that is grown for its attractive fragrant flowers both bred by Aden. This particular plant breaks the rule that white flowers are the only fragrant ones.)/ /(TRANNIE 13 -H. fortunei Albopicta flourishes for much longer in the UK than the US)/ /TRANNIE 14 H. fortunei Aureomarginata has better colour in its flowers in the UK)/

  • If they are in containers it is easier to preserve them against the only real problem that hostas have. This problem is such that it is probably one of the main reasons that the British become so dismayed with hostas.

  • The day we first proudly place our newly acquired hosta becomes the precursor to the morning that we become starkly aware that we share this country with an enormous population of molluscs. For inexperienced gardeners this can be utterly disheartening and turns many nature lovers into hardened killers of slugs and snails.

  • You will usually find that the true hosta lover will quite uninhibitedly resort to every possible deterrent and pest control available and all at the same time. Certain thick leaved varieties like Sum and Substance or Frances Williams are fairly slug resistant which is enough to supply the traditional herbaceous perennial border with the necessary foliage effects./(TRANNIE 15 Hosta enemies number 1 and 2, slug and snail on the move)/

  • In our garden we have the ultimate police force in operation in the form of a pair of Khaki Campbell ducks./(TRANNIE 16 Khaki Campbell ducks on slug patrol)./

Home for Hostas

Hostas enjoy any moisture retentive soil, enriched with plenty of organic matter especially leaf-mould. Some shade is generally appreciated during the day especially by the variegated varieties. Dont plant them in the pool, they may survive, but only just.

Plant at any frost-free time from October to March spacing plants at least half a metre apart to allow plenty of room to spread over time. Hostas only gain their full characteristics as a clump matures in its 4th or 5th year.

Mulch well in autumn

If you want to propagate hostas in early autumn or in March as the new growth appears. Dig up a moist clump and slice into the top with a sharp spade or knife. Handful size divisions showing some root can be potted into litre pots or planted out into position.

Slug Deterrents In Order of Effectiveness

  • Natural predators and garden husbandry. Going out at night with a torch and picking them up and putting them in a bucket of salt water is more effective than any amount of slug bait. Birds are particularly good at giving a hand, especially thrushes and ducks. So discourage cats. Encourage hedgehogs and toads.

  • Physical deterrents gravel mulches, sand, crushed egg shells, hair soot are all effective to a certain extent. Hostas in pots can have Vaseline or copper or aluminium tape around the rims. Sections of plastic pot or bottles around young plants helps.

  • Biological control Nematodes in a spray applied to the ground around are extremely effective for about 6 weeks but are limited by the weather and need time to show results.

  • Chemicals Last resort. Slug pellets based on metaldehyde are less toxic too wildlife than methiocarb. Aluminium sulphate based although claimed to be harmless to other species does not seem particularly effective against determined slugs.

  • Beer or milk in Slug Pubs can play their part in diverting a few wayward types but often accidentally catch a lot of the very useful ground beetles.

  • A bund of Australian kaolinite and opal powder around precious individuals is only effective until it gets very wet.
