If I buy lupins, agapanthus and foxgloves now (crocus are selling them in 9cm pots), would I be able to plant them out straightaway please? I don’t have a greenhouse and have very few window sills (sash windows). I need to buy quite a lot so don’t want to buy too early if I might plant them and lose them, or keep them in pots outside but then have to bring them in every night.
