Hostas Shade Gardening with Minnesota’s Non-Native Native David Arbeit District 10 Environment Committee Lecture Series April 14, 2013 When Will We Know It’s Spring? Emerging Hostas Will Tell Us Hosta’s for Shady Woodlands Hosta’s for Shady Gardens A Como Example Hosta’s: How They Got Here • Hostas are from Asia, where they’ve been cultivated since at least the 12th century. • Used in Japanese garden architecture because of lovely form and color. Young leaves eaten as vegetables. • Appeared in US shortly after doctor/botanist Philipp von Siebold sent Japanese hostas to Europe in 1830s. • Named for Dr. Nicholas Host (1761-1834), physician to Austrian emperor. Also known as Funkia. • Easily hybridized, there are now more than 3,000 cultivars registered by AHS. Some Hostas are Old ‘Ventricosa’ (Stearn 1931) Became known to European naturalists traveling in China during the latter part of the 18th century. Native to China and northern Korea. One of the first species to be grown in Europe. It did not receive its modern species name until 1931 (Stearn). It has widely bell-shaped purple flowers and dark green shiny leaves and makes an excellent landscape hosta. Served as the classic watercolor model for hosta painting. Some Hostas are Old and Common ‘Undulata Albomarginata’ (Maekawa 1936) Hosta ‘Undulata Albomarginata’ has been the most commonly planted hosta for the last hundred years. The dark green leaves of a young Undulata Albomarginata are thin and smooth, but it develops a slight corrugation as it matures and the white margins seem to blend into the green, creating a very pretty effect. Unfortunately slugs love it too, and without slug protection it can look pretty awful in just a few weeks. Some Hostas are Very Large ‘Empress Wu’ (Brian & Virginia Skaggs 2008) Grows 4’ to 6’ in height. One of largest new hybrids, only now becoming available. Some Hostas are Very Small ‘Teeny Weenie Bikini’ (Ed Elslager 2000) One of smallest hybrids. Grows to a couple of inches high and 4 to 6” wide. A Susan Jane favorite!! Some Hostas are Blue ‘Halcyon’ (E. Smith/BHHS 1988) Color: Blue Size: 15 x 30 Habit: Mounding Sun Exposure: Partial/Full shade Flower: Lavender Is recognized as one of the all-time finest blue hostas. Holds its color well, is a vigorous grower, has good substance, is durable, and is “gardener tolerant.” Parent of many: June, El Nino, First Frost Some Hostas are Yellow ‘Fire Island’ (Bill Brincka 1998) Color: Yellow Size: 12 x 20 Habit: Mounding Sun Exposure: Partial/Full shade Flower:Purple Origin: longipes f. hypoglauca x 'Crested Surf' Brightens up shady areas. Red petioles! “Viridescent” Some Hostas are Ripply ‘Clovelly’ (K. Terpening 05) Color: Green Size: 18 x 30 Habit: Mounding Flower: Lavender Origin: longipes f. hypoglauca x 'Crested Surf' One of best ruffled leaf edges of any hosta. Horizontally held leaves with deep piecrust edges. Even young plants show ruffling. Named for the pebbled streets of Clovelly, England because mature leaves show some pebbling or dimpling on the surface. Some Hostas are Ripply and Blue ‘Queen of the Seas’ (M. Seaver 2001) Color: Blue-Green Size: Large (48” x 24”) Habit: Mounding Flower: Lavender This spectacular hosta has lightly twisted, pointed leaves with a heavily rippled, piecrust margin and a serrated edge. It will become a spectacular plant when mature and the blue color. One of the most dramatic “piecrust edged hostas” available. Hostas of the Year In 1996, the American Hosta Growers Association established the competition for Hosta of the Year. The winner is selected to represent hostas that are: • good garden plants in all a regions of the country • widely available and in sufficient supply • retail for about $15 in the year of selection. The Hosta of the Year list is a good basis for starting a hosta collection.

The most commonly seen ones are plants of 'Gold Standard', 'Striptease', and 'Sum and Substance', but other common varieties are being reported infected in large numbers. While this disease does not kill plants, its primary danger lies in its proven ability to spread prolifically.
