Alcea 'Black Knight'

Gorgeous upright perennial with rounded light green leaves. Flowers deepest purple almost black. Height 6'. Best in an open sunny position, tolerant of dry soils.

15 seeds.

The seed we offer can be sown anytime from January to September. Sowing between January and April will require slight warmth (15°C to 21°C) to maintain germination. Later sowings from April to September will not require artificial heat, they will require protection from sudden downpours or extremes of temperature. Seed trays may dry out more easily in summer sun. Further detailed sowing information is sent with the seeds.
