Very pretty! I have not tried growing them from seed. I have been fascinated with the pink ones...I had Red Caroline for a couple years. Why do I always want the stuff that is so difficult to hybridize? Yesterday I was thinking about why there are no turquoise colored flowers (that I know of, anyway).
I am trying to reduce things this year rather than add, as my gardens are getting too crowded...but trust me, I will think about having more delphs. They are so spectacular.
