Cultivation details:

Requires a light freely-draining humus-rich loam in light shade. Prefers a neutral to acid sandy soil. Requires a warm sunny position. This species is probably hardy to about -25 if the plants are dry, but the softly hairy leaves are susceptible to rot in warm damp winters and so the plants are often grown in the greenhouse. The plants are prone to fungal infections, especially when grown in damp conditions. The Chinese foxglove is cultivated as a medicinal plant in China.

Propagation:

Seed - sow autumn or spring in a greenhouse. Prick out the seedlings into individual pots when they are large enough to handle and grow them on for at least their first winter in a greenhouse. Plant them out in late spring or early summer. Root cuttings in winter. Division in spring. Basal cuttings in late spring or early summer. Harvest the shoots with plenty of underground stem when they are about 8 - 10cm above the ground. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
