I’ve just posted Sarah Holdsworth of Bee Happy Plants some seeds from my Globe Thistles, Echinops sphaerocephalus. Recently, when they were in bloom on my allotment, there were 6 species of bee working them simultaneously! I hope Sarah can propagate them so other people can have the pleasure of watching bees in their gardens.
I have plenty of seeds left so, if you’d like some, give me a shout. The plants grow quite big – up to a fathom high and a yard wide with globular blue flower heads as big as your fist (I don’t know what that is in metric).
