description

Organic Black Opal Cherry Tomato (Solanum lycopersicum) is an indeterminate annual variety distinguished by abundant clusters of small dark purple fruits that become almost black at maturity. Very decorative in the vegetable garden, it creates a beautiful contrast with green foliage and adds an original touch to summer harvests. Its juicy flesh, thin skin, and rich, mild, sweet flavor make it an ideal cherry tomato to enjoy fresh, straight from the garden, in salads, as an appetizer, or as a colorful garnish. Vigorous and productive, it reaches approximately 1.8 to 2.1 m (6 to 7 ft) and usually produces its first fruits about 70 days after transplanting.

Organic Black Opal Cherry Tomato should be sown indoors from March to April, about 0.5 cm (1/4 in) deep, with steady warmth between 21 and 27°C (70 to 81°F) to encourage uniform germination. After the last frosts, hardened-off plants can be transplanted into full sun, in fertile, organic-rich, slightly acidic to neutral, well-drained soil. It also grows very well in a large, deep container on a sunny patio or balcony. A sturdy stake or cage is essential to support its vigorous growth. Deep, regular watering, organic mulch, and moderate fertilization ensure strong production.

In the edible garden, Organic Black Opal Cherry Tomato is as attractive as it is delicious, perfect for adding color, abundance, and diversity to vegetable beds. Its long dark clusters quickly become a visual highlight while offering an easy harvest to snack on throughout summer. It grows well alongside basil, chives, and parsley, which help create a lively and balanced vegetable garden. Its yellow flowers attract bees and other pollinating insects, supporting beneficial biodiversity and good fruit set. Frequent harvesting of ripe fruits encourages continued production until the end of the season.
