Six out of six of the Foxglove seedlings made it through the Winter. I have potted them on into 7″ ceramic pots and the roots when I lifted them were huge.
Pot up digitalis plants and grow them on in frost free conditions for transplanting outdoors later on. When plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over a period of 7 to 10 days, before planting them in borders and containers in sun or partial shade. Although foxgloves prefer a fertile, moist soil, they will happily tolerate almost any soil except those that are excessively dry or waterlogged.
Foxglove, also called Digitalis purpurea, is a common biennial garden plant that contains digitoxin, digoxin, and other cardiac glycosides. These are chemicals that affect the heart. Digitalis is poisonous; it can be fatal even in small doses. It was the original source of the drug called digitalis.
Digitalis ‘Dalmatian Mixed’ looks magnificent in cottage gardens and woodland borders but thanks to their uniform branching habit, these statuesque foxgloves make fabulous annual bedding too. These short lived perennials will happily seed about to create dramatic drifts and attract wildlife to their nectar rich flowers. Height 20″. Information from T&M.
