Solanum sessiliflorum, the cocona, is a tropical shrub belonging to the Solanaceae family. The cocona plant has sturdy branches and huge, serrate and hairy leaves. Cocona closely resembles a number of close relatives, including naranjilla and pseudolulo. It can be distinguished from those plants by its lack of spines. It will hybridize with those and other close relatives. Cocona also lacks the characteristic purple coloring usually seen in the naranjilla. Its flowers resemble large potato flowers, with light green petals. Cocona is harvested in parts of South America around the Amazon rainforest such as Purús Province in eastern Peru.
