... and a friend call me... "Hi Dave, please tell me which are the best flowering plants that I can plant in this treatment wetland? But please tell me species that bees can pollinate".
Well, in my opinion, all the flowering wetland species can be used and in particular for the local climate: Caltha
palustris, Iris pseudacorus, Iris ensata, Canna, Calla, Lythrum salicaria, Nymphaea
alba, Nuphar lutea, Pomtederia cordata, Thalia dealbata... no reeds this time!
