Additional Comments:

In 2003 and 2004 this plant stayed dormant in my garden until fall and then started growing once temps dropped. Unfortunately freezing temps arrived before the plant could bloom. The plant apparently died by autumn of 2005 as no new growth appeared this year. (D. Kramb, 23-DEC-05)
