Tomato – Big Rainbow Heirloom

🍅 Tomato – Big Rainbow

(Solanum lycopersicum)

NZ prohibited 

Striking in both appearance and flavour, Big Rainbow tomato is a standout heirloom variety celebrated for its large, multi‑coloured fruits and exceptional sweetness. Producing impressive beefsteak‑style tomatoes, this variety displays beautiful golden‑yellow skin streaked with red, with the same marbled pattern continuing through the flesh.

The flavour is rich, mild, and slightly fruity, with low acidity and a smooth, juicy texture. These qualities make Big Rainbow perfect for fresh slicing, salads, and showcasing in dishes where colour and flavour shine. Each fruit is substantial and meaty, offering a satisfying bite and excellent eating quality straight from the plant.

Growing on vigorous, indeterminate vines, Big Rainbow provides generous harvests of large, eye‑catching fruit throughout the season. It’s a favourite for gardeners who want something a little different—both visually and taste‑wise—while still delivering dependable results.
