- Description
-
The Hairy Toad Lily or Japanese Toad Lily is a native of the Japanese Islands of Honshu, Shikoku, and Kyushu. In their native habitat, they are found on shady rock cliffs or stream banks. The Genus name, "Tricyrtis," is Greek. "Tri" translated means three. "Kyrtos" means humped, referring to the nectaries which are swollen and sac-like. The species name, "hirta," means hairy which accounts for its common name, Hairy Toad Lily. Over the last 20 years, new cultivars and hybrids have been developed in Japan and the United States. Currently, many Tricyrtis species can be found at local and specialty nurseries.
The Hairy Toad Lily propagates from seeds, stem cuttings, or divisions. It has slow forming, creeping rhizomes, and develops clumps of green foliage with a spread of 18-23 inches. The unique showy flowers are white to lavender with purple speckles and bloom summer to fall.
They are very unique plants that are excellent as an accent or border plants so that they can be seen and appreciated up close. They are complementary to other shade-loving plants such as hostas, ferns, astilbe, and hellebores. They prefer slightly acid soil with high organic matter that is kept moist and not allowed to dry out. Plant in shade to partial shade.
Problems: Rabbits like to eat leaves and buds. The Tricyrtis floral virus, which is spread by aphids, causes the flower to become mottled and then turn completely purple. Anthracnose may cause small orange spots on the leaves. To prevent this fungal disease, it is recommended to keep the foliage dry and water only at the base of the plant.
