A lot of the purple flowers have died of and gone into seed which i have been collecting, the seeds are black and about 3mm, around the back end of June a same plant which was around 5ft wide x 5ft tall and covered in bees when it was in full bloom, what is it please anyone.

The plant in the foreground with purple flowers is Comfrey - bees love it - very good for adding to the compost heap - can make liquid feed from it.
