I've got three clumps of Bocking14 growing. One is at one end of my herb bed, open aspect, by a south facing wall, one is in semi shade under an apple tree, both grow like there's no tomorrow. The third clump is under (close to) mature horse chestnut trees and it struggles to make any growth at all. All the original roots were supplied by Tonybloke so I don't think there can be anything amiss there, they should all grow at the same rate. Anyone else got places where Comfry won't grow?
