Find helpful information about Black Prince Hollyhock seed germination, flower color, and plant care.
Hollyhock seeds commonly germinate in about 10–21 days under suitable conditions, although timing can vary with seed freshness, temperature, and moisture. Follow the seed supplier's instructions and keep the growing medium evenly moist during germination.
Flowering time depends on the cultivar, sowing date, and growing conditions. Many hollyhocks flower in their second year, while some plants may flower in the first year when started early under suitable conditions. Check the supplier's variety information for more specific expectations.
Provide adequate spacing and good airflow, water the soil rather than repeatedly wetting the leaves, and remove badly affected foliage. Hollyhock rust can cause orange-brown spots on leaves. Dispose of infected plant material appropriately and avoid leaving diseased leaves around the garden.
