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.

Harvesting Capsicum (Bell Pepper)
When ready: Green capsicums: full-sized, firm, glossy skin. Coloured capsicums: leave on plant 2-3 weeks past green stage until fully coloured (red, yellow, orange depending on variety). Coloured fruit is sweeter with higher vitamin C.
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.
