Alcea 'Blacknight' - Hollyhock Alcea 'Black Knight' bears incredible, single to semi-double, almost black flowers in dramatic, tall flower spikes. It's easy to grow and perfect for planting in groups at the back of a sunny border. For best results, grow in moist but well-drained soil in full sun to partial shade. Other than their fabulous blossoms, one of the best traits about this series is that the plants are truly perennial, not biennial.
