25 Seeds Black Prince Hollyhock Perennial Flower Seed

Black Prince Hollyhock is a stunning perennial (often grown as a biennial) producing dramatic, near-black, single flowers on tall spikes. Its deep chocolate-maroon blossoms, sometimes described as purple-black, create a striking contrast in cottage gardens, borders, and pollinator plantings. This heirloom variety brings old-fashioned charm and vertical interest to sunny landscapes, blooming from mid to late summer atop sturdy stalks that can reach 5-6 feet tall.

Ideal for the back of borders, against fences or walls, these hollyhocks thrive in full sun with well-drained soil. They are drought-tolerant once established and attract bees, butterflies, and hummingbirds. Flowers open from the bottom of the spike upward, providing weeks of color. Allow some seeds to fall for naturalizing, or collect them for future planting. Expect blooms in the second year after sowing.
