It's great to see such a good example of the difference that temperature makes! I always worry when first-of-season scapes don't fare well, but like you have shown, once blooming weather really hits they usually get more consistent. We are on the cusp of it right now with some opening and some shrinking back (went from average 70 degrees in April to 95 today and forecast of 80s for May)... can't wait to see more blooms to cheer us all on! Spring has sprung.
Beautiful blooms!
