Solanum quitoense is a shrub that forms numerous branches at the base. The stems are slightly lignified.

The leaves are heart shaped, coarsely toothed, up to 60 cm long and 45 cm wide on a petiole up to 15 cm long.

The whole plant, leaves and twigs, is covered with short downy stellar purple hairs on younger parts and single hairs on older parts.

The flowers appear in the leaf axils in short groups of up to 10 fragrant flowers of about 3 cm in diameter. They have five petals, white on top, purple and hairy underneath, and five prominent yellow stamens. The unopened buds are covered with purple hairs.

The fruit is protected by a brown, furry coat. When fully ripe, the hairs can easily be rubbed off. They have a bright orange, smooth, leathery and rather thick skin. The fruit is round or oval-round, up to 6 cm in diameter and contain translucent green or yellowish, very juicy pulp. The taste is like rhubarb and lime. Numerous pale seeds, 3 mm in diameter.

In its region of origin, the fruit is produced all year round, in subtropical regions annually and in temperate regions, no fruits are formed.

There are three varieties: with spines, without spines, and the third variety has red fruit and smooth leaves.
