Solanum

( soh - LAY - num )

At-A-Glance Information

This large genus of flowering ornamental and crop plants includes Tomatoes, Potatoes, Eggplants, and other beautiful species. Horse Nettles are also included in this genus. Commonly called Nightshades, these plants take on a wide range of growth habits, including shrubs, vines, trees, and subshrubs. Take care when planting these flowering, fruiting plants in the garden, as some plant parts are toxic to humans and pets when consumed.

Solanum Species and Varietals

The genus Solanum is the largest member of the plant family Solanaceae, and includes between 1,500 and 2,000 species. Recent genetic evidence has led to the previous separate genera Lycopersicon, Cyphomandra, Normania, and Triguera being added to Solanum. The genus Lycianthes, although it contains similar-looking plants, was kept as its own genus. Solanum plants can be grown in all zones (to find your zone, click here: Zone Map).

Solanum abutiloides (Dwarf Tomarillo)
​This species is endemic to Argentina and Bolivia, and is a weedy plant that thrives in poor soils on stream banks and in scrub lands. These plants quickly mature into shrubs that top out at about 30 feet tall, although they are usually seen much smaller in cultivation. Small white flowers fade to reveal small fruits that mature to orange when ripe. Unripe fruits are mildly toxic.

Solanum acaule (Wild Potato)

Solanum aculeastrum (Soda Apple, Sodaapple Nightshade, Goat Apple, Poison Apple, Bitter Apple)
This species is native to Africa. Flowers bloom from September through July in the plants' native range, and are followed by highly poisonous berries. Due to their thorns, this species is used as a livestock-corralling shrub, and is also used as a source of saponin (for making soaps). Do not consume; this species is poisonous.
