Solanum seaforthianum
Solanum pseudocapsicum
Solanum seaforthianum is widely cultivated as an ornamental and sporadically escapes in Florida. A similar species with twining petioles, S. laxum Sprengel, is occasionally cultivated in California. It is distinguished from S. seaforthianum by having tufts of hairs in the vein axils of the abaxial leaf surfaces, white rather than violet corollas, and equal stamens.

Solanum pseudocapsicum is native from Mexico to Argentina, southern Brazil, and Uruguay. It is grown as an ornamental for its showy fruits, especially around Christmas. It occasionally escapes from cultivation in southern Florida and Texas. In Texas, it has become established and fairly common in Austin, in the Lower Rio Grande Valley, and in Goliad and Caldwell counties. Cultivated forms are usually glabrous, but some can have branched pubescence. The fruits are mildly poisonous when ingested by humans but can be highly toxic to dogs and some birds.
Solanum pseudocapsicum, along with S. diphyllum, has a distinctive leaf arrangement in which a longer, narrower leaf is paired with a shorter, often more rounded one.
