Fruit Edible Annual Biennial

This is the wild plant from which many of our cultivated sweet peppers and chillies have been bred. It shows a wide range of fruit shapes, colours, sizes and degree of capsaicin production - from where the heat may or may not be felt. It has green leaves and usually white flowers, though occasionally tinged purple. It is actually a woody perennial but is almost always grown as an annual in the UK as it is hard to keep alive over the cooler months
