Unit price perLactuca sativa
Tropicana is an exceptionally heat-tolerant Crisphead Lettuce producing attractive dark green leaves with deeply curled, frilled edges. Crisp and succulent, it combines the substantial texture of a heading lettuce with the decorative appearance of a leafy variety.
The leaves have a fresh, mild flavour and satisfying crunch, making them excellent for salads, sandwiches, burgers and wraps. The heavily curled edges also add plenty of texture and volume to mixed salads.
Tropicana is particularly valued for its outstanding heat and bolt tolerance, allowing it to remain productive in conditions where many traditional lettuces quickly run to seed. Its rapid maturity of around 52 days makes it especially useful for successive sowings and extending the lettuce-growing season into warmer weather.
Lettuce is one of the world’s oldest cultivated salad vegetables, grown for thousands of years and spreading through the ancient Mediterranean world. Today its enormous diversity includes looseleaf, cos, butterhead and crisphead forms adapted to a wide range of climates and seasons.
Although Tropicana handles warm conditions particularly well, it still performs best in fertile, well-drained soil with a near-neutral pH and consistent moisture. Some afternoon shade can further improve leaf quality during periods of extreme heat.
Seed count: approximately 600–1,000 seeds/g
Approximately 60 seeds per packet

Planting / Sowing
Sow shallowly, approximately 3–5 mm deep, directly into prepared soil or raise in trays for transplanting. Lettuce seed needs only a light covering. During hot weather, germination may be improved by starting seed in a cooler, shaded position.
Space plants approximately 25–30 cm apart for mature plants. Grow in full sun during mild weather, with some afternoon shade beneficial during periods of intense heat.
Keep soil consistently moist to encourage crisp, tender growth and reduce stress. Harvest individual outer leaves as required or allow plants to mature before cutting the whole lettuce at the base.
Maturity: approximately 52 days.
Due to quarantine restrictions, TAS has an 800g limit per each seed variety and WA has a 10,000 seeds limit per variety.
