Seed - sow spring in a greenhouse and only just cover the seed. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in early summer, after the last expected frosts. Give the plants some extra protection, such as a cloche, until they are established and growing away well.
