Aubergine
Solanum melongena
A tender, upright plant of the nightshade family grown for its large fleshy fruit — most often glossy purple-black, but also white, green or streaked, and ranging from egg-sized and round to long and cylindrical. Pale mauve star-shaped flowers and soft grey-green felted leaves mark it out as a relative of tomato and potato. In Britain it is a glasshouse crop rather than a wild find, and the fruit is always eaten cooked.
Not naturalised in Britain or Ireland. Native to tropical Asia and needing sustained warmth, it is grown here under glass, in polytunnels or in pots against a sheltered south-facing wall, in rich free-draining soil; plants left outdoors rarely ripen fruit in a cool summer.
The fruit is safe once cooked; raw flesh is harsh-tasting and contains glycoalkaloids, and the leaves and stems are not edible at any stage. The calyx and stems of many varieties carry sharp spines, so cut fruit off with secateurs rather than pulling. Some people report sensitivity to nightshade-family vegetables generally.
Always use more than one reference to confirm a plant. You are responsible for what you choose to forage.
Fruit
A large, smooth-skinned berry, typically deep purple-black with a high gloss, borne singly or in small clusters and sitting in a green leafy calyx. White, lilac, green and striped forms are all the same species, so colour alone tells you nothing about variety or ripeness.
Flowers
Pale mauve to violet, about 3–5 cm across, with five pointed lobes and a stout yellow cone of anthers in the centre. The nodding, star-shaped form is typical of the nightshades and is the clearest family clue before any fruit sets.
Leaves and stems
Large, lobed, alternate leaves with a soft grey-green felt of fine hairs on both sides, on thick stems that often flush purple. Many varieties carry short sharp spines on the leaf midrib, stem and calyx — worth checking before reaching into the plant.
Habit
A bushy, upright plant usually 60–120 cm tall, needing support once fruit is heavy. It behaves as an annual in Britain, killed by the first cold nights rather than persisting as it does in its native range.
