If you deadhead astilbe, will it continue to bloom longer?
I'm interested in seeing the answer as well. Of course I have a shorter growing season so it might not be feasible for me after all. I had purchased 'White Wings' because I had heard somewhere on tv that it had the potential for rebloom but it hasn't yet for me.
Never had a rebloom on an Astilbe, but my growing season is shorter than yours also. I don't usually get reblooms on daylilies either. Not enough time.
I have 4 different varieties, and none of mine re-bloom after deadheading.
So it's pretty unanimous that Astilbe don't rebloom. I have seen a few late flowers on daylily 'Stell D'oro' but mine's in mostly shade. My neighbor does get more rebloom on his which is in full sun.
thanks so much folks. It helps me decide how to plant around it when it's idle. Although I must say, the foliage is nice.
