Penstemon grandiflorus (common name: large beardtongue)
Propagation: Seed - sow late winter in a greenhouse[1]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in late spring.
Alternatively, the seed can be sown in early summer in a greenhouse, the seedlings overwintered in the greenhouse and then planted out in the following spring[1].
Division in autumn[2].
Cuttings can be taken throughout the growing season, though August/September is best[1].
Cultivation: Succeeds in ordinary rich garden soils so long as they are well-drained[1]. Requires plenty of moisture in the growing season[1].
A very ornamental plant[1], it is very cold hardy, but some protection from winter wet is beneficial for this plant[3].
