Name derivation:
Solanum was first used by Pliny the Elder (23–79) for S. nigrum, also known as strychnos and possibly from the Latin 'sol' meaning sun; referring to its status as a plant of the sun or from the Latin 'solamen' meaning solace, comfort; referring to the narcotic properties of some species. Capsiciforme means shaped like a capsicum; possibly referring to the conical-shaped of the fruit.

Soft-wooded, short-lived erect shrub to 1 m tall, mostly glabrous. Juvenile leaves oblong-lanceolate to 8 cm long and 2 cm wide with up to 11 lobes. Adult leaves linear-lanceolate to 10 cm long and 1 cm wide, entire.Inflorescence a spike with 1-6 lavender violet flowers. Flowering mainly between September and November.

Seed cleaning:
Place the fruits in a tray and leave to dry for two weeks. Then rub the dried material by hand to remove any remaining flesh from the seeds. Use a sieve to remove the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
From one collection, the seed viability was average, at 75%.
