Cannibal Tomato — Solanum uporo

🍅 Cannibal Tomato — Solanum uporo

Scientific name: Solanum uporo
Common names: Cannibal tomato, Island wild eggplant, Uporo (traditional name)

🌍 A Rare Plant from the Pacific

The Cannibal Tomato is a tropical plant from the Solanaceae family, native to the South Pacific islands, including New Caledonia, Vanuatu, and other Melanesian islands. Known locally as uporo, it is surrounded by rich folklore. In some cultures, it was grown near ancient ritual sites—hence its provocative nickname “cannibal tomato,” which has no connection to cannibalism or inherent edibility risks when properly prepared.

🌿 Plant Characteristics

This variety produces small spherical to oval fruits, about 3–6 cm (1–2.5 in), ripening from light green to deep purple. The flesh is firm, with an intense, woody flavor featuring notes of smoked eggplant, raw cacao, and sometimes bitter coffee. Plants reach 1–1.5 m (3–5 ft) tall, with dense, velvety foliage.

✅ Edibility & Precautions

• Ripe fruits, well cooked, are edible and flavorful.
• As with many solanaceous plants, green parts (stems, leaves) and unripe fruits contain glycoalkaloids, natural compounds that can be toxic in large amounts.
  ⚠️ Never consume raw. Always cook thoroughly.

🌱 Germination & Cultivation

(Special considerations for Quebec / Canada)

Germination

• Optimal temperature: 25–30 °C (77–86 °F)
• Emergence: 7–15 days
• Method: Start indoors 8–10 weeks before the last frost. Use a heat mat or heated mini-greenhouse to ensure good germination.

Care

• Transplanting: After all frost risk has passed; grow in a greenhouse, deep container, or outdoors in very warm climates
• Exposure: Full sun, minimum 6 h/day
• Soil: Well-drained, rich in compost or well-aged manure
• Watering: Regular, without waterlogging

👉 Canada / Quebec tip:
Prefer greenhouse cultivation or mobile containers to ensure full ripening. A hot summer is required for fruits to reach maturity.
