About this cultivar:
Hosta 'Yellow Splash Rim' (v) is medium size cultivar that is a sport of Hosta 'Yellow Splash' which has yellow marginal variegation, instead of 'splashed' variegation. The plant has narrowly elliptic leaves that are slightly wavy and very shiny on the bottom. It bears purple flowers in the summer followed by viable seeds. Guess what? It has the RHS Award of Garden Merit.
According to The Hostapedia by Mark Zilis (2009), 'In 1986 the American Hosta Society decided to name and register the green-centered sport of 'Yellow Splash'. The result was that most specimens of 'Yellow Splash' became 'Yellow Splash Rim'...Increases rapidly, covering large areas of ground. Not suitable as a pot plant.'
Which is what happened with this one - we have it labelled as 'Yellow Splash' but it became 'Yellow Splash Rim' with us as it matured, so we sell it as that!

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 multiply and keep the population down - let nature run 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.
