Solanum dimidiatum Raf.
Western Horsenettle, Western Horse-nettle
Solanaceae (Potato Family)
Synonym(s): Solanum perplexum, Solanum torreyi
USDA Symbol: sodi
The leaves, petioles and branched stems of western horse nettle have sharp spines. Oval, five- to seven-lobed leaves are up to 6 inches long. Flowers are purple to violet (sometimes white) and grow at the tip in terminal clusters. Flowers give rise to ball-shaped fruits that are 0.75 to 1.5 inches in diameter and yellow at maturity.
Fruits, even though they look like tomatoes, are deadly poisonous and are probably responsible for “Crazy Cow Syndrome”.
