Aster Duchess Mixed....What do you know Alys? :)

[Ant]

Hi, I have never grown any kind of Aster before,but I have roughly 40 on the go at the moment. Half are already out in the ground with the rest in my polytunnel until I'm happy there will be no late frost to damage them. My question is; are Asters good as cut flowers from the point of cutting at the stage where the buds are just about ready to open? Thank-you for your time
