Alcea rosea 'nigra'. Tall (5 to 8 foot) spires of old-fashioned, deep maroon-black single flowers are spectacular at the back of any planting. Add the dried flowers to tea for a tangy taste and deep purple colour. Light aids germination, so just barely cover the seed. Try direct seeding or a period of cold moist stratification. Normally these will bloom the second year unless started early indoors. Short-lived biennial (sometimes perennial) will self-seed.
