Black hollyhock (Alcea rosea) features striking, deep purple-black flowers that bloom on tall spikes, adding dramatic flair to gardens. Its dark petals contrast beautifully with lighter foliage or vibrant companion plants, making it ideal for creating focal points in borders or cottage-style gardens. The flowers attract pollinators like bees and butterflies, enhancing garden biodiversity. Black hollyhock can also be used in cut flower arrangements for bold, elegant displays indoors.

ADDITIONAL SOWING INFORMATION

GROWERS TIP
Some growers soak the seed in warm water for a few hours prior to sowing. This isn’t required but can lead to better germination. If started indoors, use biodegradable CowPots, sowing 1 seed per pot, 8 weeks prior to the last frost. Transplant or direct sow when temperatures are at least 65°F. Biennials will grow a strong root system in their first year, later wilting on the surface with frost, only to return and flower in its second season.
