Hosta 'Devon Green'

About this cultivar:

Hosta 'Devon Green' is a sport of 'Halcyon' and was introduced by Roger and Ann Bowden from ……guess?....Devon. Part of their ‘Devon Series’ of Hosta this medium size plant has shiny, dark green foliage with thick substance and bears pale lavender flowers.

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Lovely in a cream stone container. Still the best-selling green-leaved hosta in Europe...Purple-dotted, dark green scapes."

From The Hosta Journal, (2002 Vol. 33 No. 2), "...'Halcyon', 'Devon Green' and 'June'...are the same hosta but with different-coloured leaves."…. now they say it I will have to investigate myself….

About this genus:

Hosta (hos-ta) is a genus of plants commonly known as plantain lilies, giboshi, or the old botanical name Funkia. The name Hosta is in honor of the Austrian botanist Nicholas Thomas Host. However most  modern plants were introduced from Japan to Europe by Philipp Franz von Siebold in the mid-19th century. Don't worry about Philipp's legacy being forgotten though; he has a species named after him! (Hosta sieboldiana). 

Hosta are often touted as the best shade-loving plants for the perennial garden, which is hard to dispute. In cultivation, Hosta readily mutate and have produced thousands of novel colours and leaf forms (blue, gold, and variegated are the most popular). Because of their great foliage Hosta are often thought of as foliage-only plants, but it is worth noting that many cultivars  have fantastic flowers - see "Sum and Substance" and "Stained Glass" for example.

You will read  that for best performance, Hosta prefer to be out of full-sun. However if you live on these islands it is doubtful you will ever get any full-sun; so you may try them in your brightest spot as long as they have some moisture. You may have had some experience with slugs and Hosta. So have we. We have found that cultivars matter (some are tastier to slugs than others) so we try to grow only slug resistant cultivars or ones that grow so many new leaves the slugs can't keep up. We've also found that by not using chemicals little mites that eat slugs eggs are allowed to multiply and keep the population down - let nature runs its course! Some slug-loving -predator should turn up eventually!

How to use Hosta? Well, if you are paranoid about slugs,  place the plant in the middle or back of the border where you can only see the upper part of the plant. Slugs don't climb so high so the lower leaves that get slug damaged won't be seen! As for plant partners we put some red stemmed dog-woods near or through them (Cornus), or large leaf -ferns. It is common to put bulbs in and around Hostas; we do it with Allium. But we don't do it with Narcissi or Tulipa; they don't like the competition!
