Beware of squirrels! Had mine one day only as the squirrels not only ate the flower but the whole plant as well - including roots!

I just purchased this plant from Heritage Perennials (June 2005) and the label lists the name as "Tricyrtis formosana 'Seiryu' " . On the back of the plant tag it states FORMERLY HATATOGISA. Just a FYI. Can't wait for the blooms to open on mine!

Positive fangNJ On Oct 8, 2004, fangNJ from New Providence, NJ (Zone 6a) wrote:

Delicate, orchidlike, deep dusty blue flowers have a white center and contrasting purple spots. The flower rise above the foliage on long, arching stems.
Perfect for shaded sites along a walk or path.
Divide in early spring while plants are still dormant.
