Descriptions (from various sources):
Light green above, glossy lighter green below. Oval to heart shaped. Undulating leaves with finely serrated margins. White flowers in September. Fertile.
Named after the islands to which it is native, this hosta is not one you'll find in most, if any, nursery catalogs. (The Tsushima Islands occur between Japan and South Korea in the Korean Strait.) Mature plants occur as tight mounds, 12" tall by 30" wide, covered in wavy-margined green leaves. However, the true glory of this hosta lies not in its foliage, but rather in its flowers. In August, many scapes (= flower stalks) arise from the crown of the foliage, reaching 24-30" in height, and are adorned by dozens of purple, nearly striped white, funnel-shaped flowers, 2" in length. Zone 6. Be the first person on your street to lay claim to this rarity.
