Solanum


n.

[L., nightshade.]
(Bot.) A genus of plants comprehending the potato (S. tuberosum), the eggplant (S. melongena, and several hundred other species; nightshade.


 
 

A widespread plant genus of the family Solanaceae which contains a number of valuable crop plants but also some poisonous ones. Poisoning may be due to (1) the presence in the plant of toxic glycoalkaloids which cause diarrhea, (2) alkamines, e.g. nitrosamines, which cause neuromuscular signs of incoordination, and the ‘crazy cow’ syndrome, or (3) calcinogenic glycosides which cause excessive deposition of calcium in tissues.
Solanaceous plants which may cause diarrhea syndrome include Solanum aculeastrum, S. americanum, S. aviculare, S. capsiciforme, S. capsicoides, S. carolinense, S. cinereum, S. dulcamara, S. elaeagnifolium, S. incanum, S. laciniatum, S. mauritianum, S. melongena, S. nigrum, S. panduriforme, S. pseudocapsicum, S. quadriloculatum, S. rostratum, S. seaforthianum, S. simile, S. sturtianum, S. symonii, S. triflorum, S. vescum.
Solanaceous plants which cause nervous syndromes include Solanum bonariensis, S. dimidiatum, S. fastigiatum, S. kwebense, S. luederitzii, S. lycopersicum, S. tenuiramosum, S. upingtoniae.
Solanaceous plants causing calcinosis include S. linneanum (S. hermanii, S. sodomaeum), S. malocoxylon (S. glaucophyllum), S. torvum.
Solanaceous plants causing miscellaneous syndromes include S. carolinense (inflammation of the mouth and esophagus), S. tuberosum (the common potato), which can cause carbohydrate engorgement. Eating of large quantities over a long period causes dermatitis of the lower limbs. Greened and sprouted potato tubers contain solanine and cause poisoning if fed without cooking or paring.

 

Potato family
Solanaceae

So-lay'num. Nightshade . A huge genus of herbs, shrubs, vines, and sometimes trees, comprising about 1700 species of nearly worldwide distribution, but overwhelmingly tropical. The genus includes the Potato and Eggplant, as well as ornamental plants for the greenhouse or outdoor culture in the South; some are pernicious weeds.

Description
Leaves alternate, the juice of the wilted leaves deadly in some species, suspect in most others. Flowers often borne in the leaf axils or near them, often solitary or in few-flowered clusters. Calyx united. Corolla regular, shallowly bell- or wheel-shaped, the 5 stamens usually inserted on its throat. Fruit edible in some species, deadly poisonous in others.

How to Grow
Start seeds indoors 8-10 weeks before the last spring frost. If given heat of 75° F (24° C), seeds will sprout in 10-14 days. Set out in the garden when the soil and weather are warm. In cool climates, a black-plastic mulch is recommended. The species below prefers warm weather.

Solanum Melongena'Golden Eggplant'
Ornamental Eggplant . To 2 ft. (60 cm) high, with angled or lobed leaves. Flowers violet-purple, nearly 2 in. (5 cm) wide, usually nodding. Fruit 3-5 in. (7.5-12.5 cm) wide, white turning golden yellow. Africa, Asia. Several other cultivars available. Tender annual.

Solanum is a large, variable genus of annual plants and perennial plants, forbs, vines, sub-shrubs, shrubs, and small trees. They often have attractive fruit and flowers. Most are poisonous, but many bear edible fruits, leaves, or tubers, and the genus includes several cultivated species, including three major food crops:

  • Tomato, Solanum lycopersicum (sometimes classed as Lycopersicon lycopersicum)
  • Potato, Solanum tuberosum
  • Eggplant, Solanum melongena

Solanum species are used as food plants by the larvae of some Lepidoptera species - see list of Lepidoptera which feed on Solanum.
