About Solanum cajanumense
Casana (Solanum cajanumense) is a small shrub or tree from the Solanaceae family, native to South America, valued for its edible, sweet-and-sour, tropical-flavored fruits. It features large, velvety leaves and purple flowers that give way to round or oval yellow or orange fruits. This ornamental and fruit-bearing plant looks spectacular in tropical orchards or as a specimen plant in spacious gardens.
Native range
Andean region of South America, specifically in Peru, Ecuador, and Colombia.
Care tips
It requires full sun to partial shade for optimal fruiting, and regular watering to keep the substrate moist but not waterlogged, especially during flowering and fruiting. It prefers well-drained, slightly acidic soils rich in organic matter. A common mistake is neglecting pruning, which can lead to unruly growth and reduced fruit production; annual shaping and maintenance pruning is recommended.
