Capsicums are warm-season Solanaceae closely related to chillies, tomatoes and eggplant. They need a long, warm growing season to produce well. The coloured varieties (red, yellow, orange) are simply mature green capsicums left on the plant longer. A staple of Australian home gardens in warm and temperate zones.

How to harvest: Cut with sharp secateurs leaving a short stem. Do not pull - this damages the plant. Harvest in morning when firm and cool.
