Discussion

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 marginatum is naturalized along the central and southern coast of California, where it has been listed as a noxious weed by the California Department of Food and Agriculture. There are few recent collections.
