Noteworthy Characteristics

Tricyrtis, commonly called toad lilies, is a genus of about 16 species of herbaceous perennials from the Eastern Himalayas to the Philippines. They are valued garden plants in large part because of their unique flowers, ability to flower in shade and late summer to fall bloom time.

Genus name comes from the Greek words tri- meaning three and kyrtos meaning humped as the bases of the three outer petals are swollen and sacklike.

Common name presumably relates to the spotting on the flowers.

‘Sinonome’ is a hybrid cultivar that typically grows in a vase-shaped clump to 30-36” tall on upright stems slightly arching near the top. In optimum growing conditions, it will spread by rhizomes to form large colonies. It features small, creamy white, lily-like flowers (1” long) with burgundy-purple spotting and blotching. Flowers appear in clusters in the upper leaf axils and stem tips. Flowers bloom in late summer to fall (early September into October in St. Louis). Each flower has six showy tepals (similar appearing sepals and petals). Ovate, medium green leaves (to 4” long). ‘Sinonome’ has reportedly been a popular selection of the cut flower industry in Japan for a number of years now due to its long flowering stems. Some nurseries sell this plant as T. sinonome.


No serious insect or disease problems. Slugs and snails are occasional visitors.


Borders, woodland gardens, shade gardens or naturalized areas. Best sited in areas where they can be observed at close range because the beauty and detail of the small flowers tends to get lost if plants can not be examined and appreciated close up. Good cut flower.
