PlantFiles: Toad Lily
Tricyrtis ohsumiensis

This plant is very vigorous and I have divided a few plants into many different patches. Have flowers that look like orchids up close. Very zone Minnesota 4 hardy compare to other species. The few other purple flower species or cultivars tend to die after three or four years for me after starting to spread well. Could be too low temperature or disease? The only purple flower to survive for me is a cutivar by the now dead Rice Creek Nursery "Rice Creek" which is a dwarfer form but it's barely spreading but I have it for 5-6 years now on shaded rock garden slope. Seedheads held up for longer period of time until heavy snow crush them. Look good with medium to large hostas as they bloom during early summer while most hosta bloom mid to late summer and grows to about 1 1/2 to 2 feet tall. Likes neutral or alkaline soil compare to other species.
