This splendid perennial plant from the Lower Danube, is related to hollyhocks and can flower the first year from seed if sown early. It can grow up to 8ft high with unusual, vine-like leaves and large, showy, cup-shaped, white or pale rose-pink flowers from July to September.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
