This one is lovely, not too tall at around 24" and hasn't needed staking despite high winds over the last couple of days. Its first bloom opened fully April 27 2005 in Keller Texas. It is growing in partial shade.

Gorgeous blooms for 2 weeks in April with little maintentance. Gets big quickly and I'll probably have to divide it this year. Also wish the blooms lasted longer than 2 weeks.
