Agastache Black Adder
I bought three of these last September and they carried on flowering for weeks. I was looking forward to enjoying them again this year, but by the first week of June they were not showing any signs of life, so I dug them up and replaced them with purple salvias (not nearly as exciting). I would like some more ABA's for their form, colour and bee friendliness, but I don't want to risk losing them again. Any advice would be welcome!
