American Black Nightshade - Solanum americanum




"Solanum americanum is a ANNUAL growing to 1 m (3ft 3in). The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects."[PFAF]
"Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers moist soil."[PFAF]



"Leaf and fruit are toxic. However, with ripening, the fruit looses more and more of its toxic character. By boiling, the plant looses much of its toxicity. The plant is therefore not generally regarded as dangerous. Furthermore, the alkaloids are poorly absorbed and rapidly detoxified by the human body (SEAFORTH, ADAMS & SYLVESTER 1983)." [Roth SAMP]

Edible Uses

"Leaves and young shoots are eaten as potherb, leafy vegetables..., as spinach or in soups.... In Hawaii, the leaves and tender stems cooked as substitute for poi, berries eaten raw." [EMNMPV.6] "The leaves are cooked as soups or eaten fried with eggs. The vegetable is found in country markets and is eaten in great quantities. It is particularly consumed during convalescence and during recuperation from diverse diseases." [Roth SAMP]

Medicinal Use





"We have very little information on this species and do not know if it will succeed in Britain, though it should be possible to grow it as a spring-sown annual. The following notes are based on the general needs of the genus. Succeeds in most soils[1]." [PFAF] "


"Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and plant them out after the last expected frosts." [PFAF]
