Black Hollyhock Care and Guide
Black hollyhock (Alcea rosea ‘Nigra’) is a tall, stately flower that is known for its deep, dark blooms. It is a biennial plant, which means that it grows from seed in the first year and flowers in the second year. Black hollyhocks can grow up to 6 feet tall, and their flowers can reach 4 inches in diameter. The flowers are typically single, but there are also double-flowered varieties available.
Black hollyhocks are native to Europe and Asia, but they are now grown in gardens all over the world. They are a popular choice for cottage gardens, borders, and cutting gardens. Black hollyhocks are also attractive to butterflies and other pollinators.
Growing Black Hollyhocks
Black hollyhocks are relatively easy to grow. They prefer full sun and well-drained soil. They are not very drought-tolerant, so they should be watered regularly during the summer months. Black hollyhocks are susceptible to rust and mildew, so it is important to plant them in a location with good air circulation.
To plant black hollyhocks, sow the seeds in the spring about 2 weeks before the last frost. The seeds should be planted 1/2 inch deep and 12 inches apart. Black hollyhocks will bloom in the summer of the second year.
Caring for Black Hollyhocks
Once black hollyhocks are established, they are relatively low-maintenance plants. They should be deadheaded regularly to encourage more blooms. Black hollyhocks may need to be staked if they are tall.
Harvesting Black Hollyhocks
Black hollyhocks can be harvested when the flowers are fully open. The flowers can be used fresh or dried. To dry the flowers, simply hang them upside down in a cool, dark place.
