Solanum wallacei

Solanum wallacei, also known as Wallace's nightshade, Catalina nightshade, Northern island nightshade, or Wild Tomato, is a perennial plant that produces purple flowers, but otherwise resembles a tomato plant. The foliage and purple-black berries are poisonous.

This rare plant is native to canyons and hillsides on Santa Catalina and Guadalupe Islands. It blooms in April and May.

Wallace's nightshade is named for William Allen Wallace (1815-1893) who collected samples from the Los Angeles area around 1854. Also named for him, Eriophyllum wallacei, the woolly daisy, among others.
