About Black Plum Tomato

Black Plum Tomato (Solanum lycopersicum) is a striking and productive variety that earns its place in any vegetable garden. The decorative 5cm (2in) plum-shaped fruits ripen to a rich mahogany colour with dusky green shoulders, offering a sweet, tangy flavour that’s perfect for fresh eating, sauces, or roasting.

This semi-determinate variety combines compact growth with a heavy, consistent yield throughout the growing season. Its unique appearance and robust taste make it an exceptional choice for gardeners and chefs alike.

Where Can You Grow Black Plum Tomato

Black Plum Tomato thrives in Zones 3-9, requiring full sun and well-drained soil. It grows well in garden beds, raised beds, or large containers, with moderate staking to support the semi-determinate plants.

History and Historical Uses

Black Plum Tomato is cherished for its unique appearance and versatile culinary uses. With origins in Eastern Europe, this variety has gained popularity for its reliable yields and complex flavour, making it a favourite for sauces, salsas, and garden-fresh meals.

5. Harvesting: Pick fruits when fully ripe, mahogany in colour, and slightly firm to the touch.
