Geographical Distributions

The origin of Solanum ferox is unknown. It is distributed from India to New Guinea, including all Southeast Asian countries, and it occurs wild and culti­vated. It is closely related to the South American S. candidum Lindley, but has never been reported from South America.


Solanum ferox is a herb or small shrub that can grow up to 1(-2) m tall. It is densely stellately pubescent, and armed with straight sharp prickles or unarmed.

The leaves are broadly ovate, measuring 5-40 cm x 3-40 cm, markedly dis­colorous and shallowly pinnatilobed. The petiole is 5-16 cm long.

The inflorescence is up to 10-flowered. The pedicel is up to 2 cm long, and armed or unarmed with prickles. The sepal is broadly bell-shaped, envelops the fruit partly or completely, and armed or unarmed with prickles. The petal is star-shaped, white or purple.

The fruit is spherical, measures 1.5-3 cm in diametre, yellow, densely pubescent with long white stellate hairs and becoming hairless. The pale yellow seed is 2-2.5 mm long.

Ecology / Cultivation

Solanum ferox occurs wild in the Asian tropics in forest openings, on disturbed sites and in sec­ondary thickets, often in shady sites, up to 1500 m altitude.
