Solanum pseudolulo

Solanum pseudolulo is a subtropical perennial plant native to northwestern South America, where it is known as the pseudolulo and occasionally as lulo de perro. It is a large herbaceous plant or small shrub with heart-shaped leaves, and its leaves and stems are covered in short hairs while the whole plant is often armed with sharp spines. The fruit is a large berry that is green when unripe and turns yellow or yellow-orange as it ripens, with orange or yellow flesh full of small seeds and a coat of hairs that detach once the fruit is ripe. The fruit is edible but regarded as inferior to that of the true lulo, the naranjilla, and it is only occasionally sold in markets. The plant is rarely cultivated; instead it spreads as a weedy species at medium altitudes in Colombia and Ecuador, where it is generally tolerated as a garden intruder and does better in sunnier places than the naranjilla. Within the genus Solanum it belongs to the Lasiocarpa clade of the leptostemonum clade, alongside relatives such as Solanum quitoense and Solanum lasiocarpum.
