Bee Friendly Flowers for Cutting

Personally I think there should be a warning posted on some of the threads on here, WARNING THIS THREAD MAY CAUSE YOUR WALET TO GET THINNER, in my case my mattress gets lower
I had never given asters a thought till I read Scarlets post re. asters, so had to go and look them up, the last time I tried asters would have been in the sixties (no Veggie I rushed home from school to check on them ) though nice flowers didn't last that long so stopped growing them, now I find that there has been a lot of work put into them, so now want to give them a try, all I need to do now is find the cheapest supplier
