Texas Nightshade
Solanum triquetrum
A native, low sprawling perennial nightshade of the south-central United States and northeastern Mexico that can also scramble upward to roughly 2 m when given a support such as a fence or shrub to climb. Small white to lavender-tinged flowers with bright yellow anthers appear nearly year-round, followed by red berries that ripen from green and are taken by birds. Unripe fruit and other plant parts carry toxic glycoalkaloids typical of the genus, documented as poisonous to cattle and dangerous to children if eaten. Tolerates full sun to partial shade and drought once established, in mildly acidic to mildly alkaline, well-drained ground.
