The Black Hollyhock (Alcea rosea) is distinguished by its striking, deep burgundy to almost black flowers, which set it apart with a dramatic contrast against white backgrounds. This variety of hollyhock is particularly favored for its ability to create a vertical accent, often reaching tall heights, making it a perfect backdrop or focal point in borders, cottage gardens, or along fences where its tall spikes can be showcased against the sky.


As a biennial, the Black Hollyhock produces lush foliage in its first year and spectacular blooms in the second. It's not only visually appealing but also functional in attracting pollinators; bees and butterflies are particularly fond of its nectar-rich flowers, making it a beneficial addition for those interested in supporting local wildlife. This plant is relatively easy to grow, preferring full sun and well-drained soil, though it's quite adaptable and can tolerate less-than-ideal conditions, which adds to its popularity among gardeners of all skill levels.

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.
