For maximum freshness, please keep seed refrigerated in its original packaging until it is time to plant. Sow seed in containers in the spring when you would normally start tomatoes or other tender annual plants, using a soil-less seed compost. Cover with perlite or vermiculite and place under protection at 21 degrees Celsius. Plant out when night temperatures do not drop much below 10ºC (50ºF). Grow on in neutral to acidic sandy soil with good drainage. Must be grown in full sun for flowers to develop in temperate regions.
