I have a tall burgundy double hollyhock and a white hollyhock with stunted growth.
A neighbour has expressed interest in some seeds for her London dial-a-ride driver, which I was happy to oblige.
Some of the seedheads have been on the plant for at least 2 months when the first sets started to die.
What colour shold they be when harvested. They have remained a light brown colour?
I ask, as it seems a long time and the plants (especially the tall one) look an eyesore in a heavy pedestrian and road traffic area on the estate.
