Harvest Tips
Harvest berries when they are fully black and slightly soft to the touch. Gently twist or cut berries from the plant. Only eat fully ripe berries—green or partially ripe berries contain solanine, a toxic alkaloid. Berries do not ripen after picking. Harvest regularly to encourage continued production. Peak harvest occurs in mid to late summer.
Fun Facts
- 🌱 Black Nightshade is one of the most widespread plant species globally and has been cultivated for food in Africa, Asia, and South America for thousands of years.
- 🌱 The plant is extremely productive—a single plant can yield hundreds of berries throughout the growing season, making it one of the highest-yielding vegetable crops per square foot.
- 🌱 All parts of the plant except fully ripe berries contain solanine, a bitter alkaloid that protects the plant; ripe berries are safe because the solanine breaks down as they mature.
