Purple Nightshade (Solanum xanti) is a poisonous shrub with deep blue purple flowers blooming from winter through spring. Purple Nightshade has dark green foliage, and the form is loosely spreading or trailing. To promote a bush form, prune leggy branches in late summer or fall.

This plant likes sun to part shade in coastal gardens and shady spots inland. It is very drought tolerant but will tolerate modest summer watering. Though it prefers rocky soil or loam, it will grow in any relatively well drained soil.

It is noted for being deer resistant and hosts numerous moth and butterfly species.
The green berries, though toxic to animals, attract birds.
