When to plant nasturtium in Darwin
Honest answer: nasturtium is a poor fit for Darwin. Nasturtium can't handle the heat in your area — temperatures exceed 30°C for too much of the year. If you're set on trying, treat it as an experiment — a sheltered microclimate or pots you can move may stretch the rules.
