About

Phacelia cicutaria, with the common names caterpillar phacelia or caterpillar scorpionweed, is an annual species of Phacelia.

It is native to California, southern Nevada, and Baja California. It grows mainly in chaparral habitats, frequently in burnt areas or on rocky slopes.

How to grow it

Phacelia cicutaria is cultivated as an ornamental plant, in native plant and wildlife gardens, and for natural landscaping designs and habitat restoration projects. Its drought tolerance makes it well suited for water conserving gardens.

It can be propagated by seed, germination of which may be stimulated with aqueous extracts of charred wood, or the charred wood itself.
