How to grow foxglove (Digitalis purpurea)

Digitalis purpurea · common foxglove

Foxglove (Digitalis purpurea) — a biennial woodland flower, 0.6–1.5 m tall, that makes only a rosette of downy leaves in its first year and in the second sends up a one-sided spike of hanging, tubular pinkish-purple or white flowers spotted inside. All parts are highly poisonous to people, and to cats, dogs and horses. Foxglove grows best in partial shade. Water it about every 7 days while it grows.

Growing notes

Light

Dappled or light shade, as in a woodland glade; afternoon shade is best. It tolerates full sun if the soil stays moist.

Soil

Moist but free-draining soil rich in organic matter, on the acid side; it grows in almost any soil except very wet or very dry. Dig in leafmould or garden compost before planting.

Care

Sow in spring on the surface of the compost without covering the seed — it needs light — and expect seedlings in two to three weeks. Plant out 30–35 cm apart; crowded rosettes wait another year to flower. Keep new plants watered for the first months, after that only in long dry spells; pots need regular watering. Protect young plants from slugs and snails. Cut the spent spike at the base to stop seeding, but leave a few to self-sow if you want new plants every year — a plant usually dies after flowering. Wear gloves when handling plants and seed. Watch for aphids on the spikes, and powdery and downy mildew.
