Nigra Hollyhock

30-35 Seeds Alcea rosea ‘Nigra’ (Hollyhock, commonly called Black Hollyhock) is a dramatic biennial or short‑lived perennial valued for its tall spires of deep, near‑black to dark maroon single flowers and lobed foliage. Native to temperate Eurasia, hollyhocks are classic cottage‑garden specimens often used along fences, walls, or the back of borders for vertical impact.

Plant ‘Nigra’ in full sun for best flowering; it tolerates light afternoon shade but performs poorly in soggy conditions. It prefers rich, well‑drained garden soil with consistent moisture and good fertility—amend heavy clay with compost to improve drainage. Because the spikes can become top‑heavy, provide staking or wind protection and maintain good spacing to reduce rust and mildew problems.

Seeds can be started indoors 6–8 weeks before the last frost or direct‑sown in spring after the danger of frost. Sow seeds just beneath a thin layer of soil or on the surface and keep evenly moist; they typically germinate in 7–21 days. Cold/winter stratification isn’t required but autumn sowing or exposure to a cool period can improve stand establishment. Thin or transplant seedlings to maintain airflow and reduce disease.

Mature plants commonly reach 4–8 feet (1.2–2.4 m) tall with a spread of about 1–2 feet (30–60 cm); space plants roughly 18–24 inches apart. ‘Nigra’ is grown primarily as an ornamental for bold vertical color, attracts bees and other pollinators, and can be used for short‑term cut flowers though it’s best showcased in the garden. Hardy generally in USDA zones 3–8.
