Tricyrtis Species, Yellow Toad Lily

I just got two of these and planted them this spring (2010). They are growing well and look like they are ready to bloom; there are man...Read Morey buds forming. I am pleasantly surprised that I will see flowers already this year. I also like it that they bloom earlier in the year than other toad lilies.

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.
