About this cultivar: Hosta ventricosa is a large, naturally occurring plant that is native to China and North Korea. It grows in a rounded mound of thin, smooth, shiny, broad-ovate, dark green leaves with widely spaced veins and undulate margins. Leaves develop strong ribbing as they mature. Bell-shaped, purple to violet flowers bloom in late summer to early autumn on upright, leafy, burgundy-spotted, pale green scapes. Specific epithet means having a swelling on one side. Offff, bit dry there... It might just be the species but still has the Royal Horticultural Society Award of Garden Merit. Position: Full sun, partial shade, full shade Soil: Almost any soil, grows well in Ballyrobert Flowers: July, August Other features: Royal Horticultural Society Award of Garden Merit (RHS AGM), Grows well in Ballyrobert, Interesting Foliage or Fruit, Suitable for Container, Dappled Shade or Full Shade Loving Hardiness: H7 - Hardy in the severest European continental climates (< -20°C), Fully hardy - grows well in Ballyrobert Habit: Clump forming Foliage: Deciduous Height: 60 - 75 cm (2 - 2.5 ft) Spread: 75 - 120 cm (2.5 - 4 ft) Time to full growth: 2 to 5 years Plant type: Herbaceous Perennial Colour: Green, purple Goes well with: Cornus, ferns, allium 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.
