Description: D. purpurea f. albiflora is a biennial or short-lived perennial, with softly hairy leaves and tall, one-sided spires of pendant, tubular, creamy-white flowers 6cm long.
Care: Grow in almost any soil, but avoid very wet or very dry situations. Prefers a humus-rich soil in partial shade but will grow in full sun. Deadhead after flowering to avoid problems with excess numbers of seedlings. Propagate by seed sown in-situ in late spring. Alternatively sow in seed trays in late spring and plant out to final position in late summer. Cut back after flowering.
