Overview

Cucurbita pepo 'Black Beauty' is a compact, bush-type summer squash cultivar prized for its prolific production of dark green zucchini fruits. This annual vegetable forms a dense, non-vining plant with large, deeply lobed leaves that are medium to dark green with distinctive silver-white mottling along the veins. The sturdy stems are thick and hollow, supporting the plant's vigorous growth habit. The cultivar produces bright yellow, trumpet-shaped flowers that are monoecious, with separate male and female blooms on the same plant. Female flowers develop into the characteristic cylindrical fruits that are harvested when young and tender, typically 6-8 inches long. The fruits have a glossy, dark green skin that is nearly black in appearance, giving this cultivar its distinctive name. Cucurbita pepo 'Black Beauty' is particularly valued for its early maturity, consistent fruit shape, and excellent flavor when harvested at the proper stage.

Native Range

Cucurbita pepo is native to North America, specifically originating in the regions of Mexico and Central America where it was first domesticated by indigenous peoples thousands of years ago. The species has been cultivated and bred into numerous varieties, with 'Black Beauty' being a modern cultivar developed for improved garden performance.

Suggested Uses

vegetable gardens, raised beds, container gardening, small space gardens, succession planting

How to Identify

Cucurbita pepo 'Black Beauty' can be identified by its compact, bushy growth habit without trailing vines, distinguishing it from vining squash varieties. The large, palmately lobed leaves show characteristic silver-white veining patterns against dark green foliage. Key identifying features include the thick, hollow stems, large yellow flowers with five pointed petals, and the distinctive glossy, dark green to nearly black cylindrical fruits. Unlike other zucchini varieties, the fruits of 'Black Beauty' maintain their dark coloration even when young, and the plant typically remains under 3 feet in spread, making it ideal for smaller garden spaces.

Care & Maintenance

Care Guide

Cucurbita pepo 'Black Beauty' requires consistent moisture throughout the growing season, with deep watering 1-2 times per week providing approximately 1-2 inches of water weekly. Apply a balanced fertilizer at planting and side-dress with compost or a nitrogen-rich fertilizer when flowering begins. Mulch around plants to retain moisture and suppress weeds, keeping mulch away from the stem base to prevent rot. Monitor regularly for common pests such as squash bugs, cucumber beetles, and squash vine borers. Harvest fruits when they are 6-8 inches long and the skin can still be easily punctured with a fingernail for best flavor and texture.

Pruning

Cucurbita pepo 'Black Beauty' typically does not require pruning due to its compact, bush-type growth habit. Remove any damaged, diseased, or yellowing leaves promptly to maintain plant health and improve air circulation. Harvest zucchini fruits regularly every 2-3 days to encourage continued production, as leaving mature fruits on the plant will reduce overall yield. If growing in very humid conditions, selective removal of some lower leaves can improve air circulation and reduce disease pressure.
