Plant Description

Common Name(s):Purple Nightshade
Scientific Name:Solanum xanti
Plant Type:Shrub
Size:up to 36 inches
Habitat:Sage, chapparal
Blooms:December to June

One of the few plants to be found in bloom this early in the year is Purple Nightshade. It is an evergreen shrub up to 3 feet high and wide, displaying purple flowers about one inch in diameter. It is commonly found blooming from January to May in sage or chaparral.

Purple Nightshade's thin leaves are about 2 inches long, oval in shape and spiral alternately up the stem. The purple flower petals are complemented by yellow anthers that gather at the center. Each of the five petals has a pair of green spots surrounded by white at their base. The flowers are followed by pea-sized purple berries. The plant often has a subtle glittery or fuzzy appearance. All parts of this plant are poisonous, like most plants in this family.

Other plants in the Nightshade family that are common in the Santa Monica mountains include Jimson weed, the non-native Tree Tobacco, and White Nightshade. Purple Nightshade is one of several Solanum members which are also cultivated for ornamental uses. While most of these are poisonous - [this one contains toxic alkaloids], there are some edible members of Solanum: eggplant and potato.

Interesting fact: Purple Nightshade are "buzz-pollinated". Native bees (not the common European Honey Bees) have evolved along with this plant to vibrate their flight muscles at a certain frequency to force the pollen from the anthers!
