Cucurbita pepo 'Black Beauty'
Black Beauty Zucchini
Open-pollinated cultivar (AAS 1957); the species C. pepo is native to Mexico and the southern USOverview
Cucurbita pepo 'Black Beauty' is Black Beauty zucchini, a bush-type summer squash annual growing 18-24 inches (45-60 cm) tall and 36-48 inches (90-120 cm) wide. Glossy dark green (nearly black) cylindrical fruit 6-8 inches (15-20 cm) long and 2 inches (5 cm) diameter, maturing in 45-55 days from seed. Bright yellow trumpet-shaped monoecious flowers 3-4 inches (7-10 cm). Dark green deeply lobed leaves with silver-white vein mottling. In the gourd family (Cucurbitaceae). Open-pollinated (AAS 1957). Monoecious: male flowers appear 7-10 days before the first female flowers — no fruit set during this initial male-only phase. Requires bee pollination. One of the most prolific summer squash cultivars: a single plant can produce 6-10 pounds (2.7-4.5 kg) per season. The flowers are also edible (stuffed squash blossoms). Harvest every 2-3 days at 6-8 inches (15-20 cm) — overripe fruit left on the plant reduces new fruit production. The prickly stem hairs cause skin irritation — wear gloves when harvesting. Squash vine borer (Melittia cucurbitae), squash bugs (Anasa tristis), and powdery mildew (Podosphaera xanthii) are the primary threats. Not deer-resistant. Non-toxic (edible crop). Native. Full sun. Tender annual. Growth rate is fast.
