The wild heliotrope is one of the most abundant flowers of midspring, especially in the south. It affects the gravelly banks of streams or the sandy soil of mesas; or grows all along the railroad embankments, making great mounds of foliage, thickly sown with the bright violet-blue blossoms; or it may often be seen clambering up through small shrubs, seeming to seek the support of their stiff branches. It is needless to say that this is not a true heliotrope, but belongs to the closely allied genus, Phacelia.
The specific name, tanacetifolia, meaning with tansy-like leaves, is more applicable to the var. tenuifolia, Thurber. Among the Spanish-Californians it is known as “vervenía.”
It is a very important honey-plant.
P. Douglasii, Torr., is a species with lavender corolla with much the aspect of the baby-blue-eyes. This is common in the western part of the State, south of Monterey, and is found sparingly north of that point.
