About
Solanum incanum is a prickly perennial shrub or subshrub, typically growing 0.4–3 metres tall, with stems and ovate leaves covered in dense, stellate hairs and often armed with sharp conical prickles. Its star-shaped flowers range from pale blue to mauve or purple, yielding spherical, bitter berries that ripen from green to yellow. The fruits are notably toxic and should not be consumed.
Where it works in Kilifi
This hardy species is well-suited for restoration efforts in degraded areas or as part of a wilder landscape on the Kilifi coast, as it thrives in dry, disturbed, and low-fertility soils. Given its prickly nature and potential to become invasive, careful placement away from high-traffic garden paths is recommended.
Growing notes
Once established, Solanum incanum exhibits excellent drought tolerance, requiring minimal watering. To enhance germination rates, seeds benefit from a 24-hour soak prior to sowing. Caution: All parts of the plant, especially the ripe fruits, contain toxic glycoalkaloids and are not suitable for consumption; the species can also be invasive.
