Black Hollyhock

100 seeds

To seed Black Hollyhock (Alcea rosea), choose a sunny spot with well-draining soil. Sow the seeds about 1/4 inch deep and lightly cover with soil. Keep the soil moist but not waterlogged. Germination typically occurs in 14-21 days. These tall, striking plants produce dark, almost black flowers on strong stems, adding drama and height to gardens. Black Hollyhocks thrive in full sun and well-prepared soil and are great for cottage gardens or as a focal point in perennial borders.
