Phacelia crenulata Waterleaf Family
PHACELIA
[67.] Nama
In favorable years these ground-hugging plants form broad, colorful mats, but in dry seasons these annuals may be tiny, each with a single flower almost as large as the rest of the plant. Flowering from February to May, bloom is heaviest in March and April. This species, also called “purplemat,” is common on flat, sandy, open desert soils from southeastern California and Baja California to southeastern Arizona at elevations below 3,500 feet. Because of its low-growing habit, nama requires that you lie prone to examine it closely, hence is one of the many small desert herbs called “bellyflowers.”

Believed to be the original host of the Colorado potato beetle, this annual is a pest on rangelands because of its spine-covered stems and fruits. Spines are long, straight, sharp, and straw-colored. It is common on desert plains and mesas at elevations from 1,000 up to 7,000 feet, blooming from June to August. The leaves and unripe fruits of this and several other species are reportedly poisonous, as they contain an alkaloid, solanin.
