The Echinacea Purpurea planted out last month appear to be doing okay; the flowers that were there when I obtained them are dying off, but new ones are appearing and some are shooting to the heights that they say they would. The test will be the over-wintering.
Butterlies and Bees appeare to love them, and they are located not a million miles away from the Buddlieia that we planted a year or so ago.
