Gardeners' Notes:

I prefer this Tricyrtis because of its deeper colored blooms. Blooms September - November in my garden.

I have had this plant for 4 years and am always surprised to see it in bloom in late Sept. or October (today 10/12), There are usually 4 - 5 flowers before it passes. The excitement of my gardening season is bookended by the appearance of the Trout Lily in May and the Toad Lily in the fall.

Our garden is in western MA - zone 5a, where nothing is for certain especially frost.

10/11/10 So far the response I'm submitting is neutral. I've had the plant for 1.5 yrs. now. I live in Ravenel, SC 10 miles south of Charleston. I have the plant in moderate shade with plenty of moisture and some grass clippings as mulch.

As the plant got to its mature height of about 30" it began to flower, just as everyone describes, then the whole plant collapsed under its own weight in July.

July here marked very very heavy rainfall, too much water is the likely cause of the collapse. But, not to worry, the flowers maintained as did the stalks and leaves, it's just that now the plant was laying on the ground.

Then, after about two weeks, new growth in the center of the plant at its crown began. I guess it was the plants way of preparing itself for the oncoming very mild winters and for aggressive growth next spring.

Try it... you'll like it.

Neutral Baa On Jan 11, 2003, Baa wrote:

A stoloniferous perennial from Taiwan.

Has ovate or lance like, deep green, spotted purple leaves borne alternately on hairy stems that grow in a zig zag pattern. Bears white or light pink flowers heavily spotted with purple.

Flowers August - October

Loves a leafy, well-drained, moist soil in a shady sheltered position. In cold regions it might need a deep winter mulch.

Slugs and snails may damage the yound leaves but they recover from a moderate attack quite easily. Look out for vine weevils in the roots.
