Michelmas Daises (Aster) purple WD3 (Heronsgate WD3)

Hi. These have just been dug up from a tub. There are currently in a sac and have loads and loads of roots. They spread rapidly and flower later in the year. I kept them in a large tub to keep them contained but they have outgrown it now. Collection from Chorleywood. I can split the sac into smaller bags as there is a lot of them, according to interest. Please time and date of collection in your reply. It can be today if wished. Thank you
