I always take advantage to this sale! Planned to stay up late and get my order in, 11 pm in CO so shouldn't have been that hard, next thing I knew it was 2 am! Still managed to get Icarus, new to me, Alice Harding and Vesuvian for the rock planting spots leading down to the back yard behind the new house, and Tranquil Dove to replace the one that died.
Zellycat, Hillary and GES didn't bloom at the same time in my CO garden but they were in different parts of the yard. I had the same plants opening 2 weeks different between the front and back beds due to shady winter conditions in the back. Hopefully someone else can confirm or debunk my statement about different bloom periods, can vary from micro-climate to micro-climate, though.
Helen, I've never seen a Yellow Bird bloom IRL so no help. Don't even remember seeing it at spring convention competition, kinda weird. That alone would've made me grab that one up if I were looking for herbaceous this year.
