Really! Never realised it was so pretty, is it the sort of thing you can get at the Garden Centre? Or should I look for seeds? Thanks so much for your quick response Dove.
It’s at the other end of the allotment but if it self seeds I will be happy it is stunning. The photo doesn’t really do it justice the flowers are a rich purple.
Debs - beautiful and beloved by bees it may be but it is a downright thug. As @B3 has hinted, it will find its way to you and you will never get rid of it. There is a very well behaved relative called Bocking 14 which does not spread and that would be the one to go for. Of course that one might be Bocking 14 so I'd have a word with the allotment holder.
Cacoethes: An irresistible urge to do something inadvisable
Thanks LB it is only a single plant growing right at the edge of the plot near the path and I always stop to admire it since it started to flower. I never see that holder so can’t ask them but if it self seeds I may just take a single flower and try it in a pot I will look out for seeds for sale first though.
There are Comfreys bred for making composts that don't seed, Bocking (plus a number) It may be one of these and it's one worth getting if you don't want the seedlings everywhere. I'm told it's just as good for insects
