'[1] Phacelia tanacetifolia is an annual that grows erect to a maximum height near 100 cm (40 in) with none to a few branches.

The leaves, 20–200 mm (1–8 in), are mostly divided into smaller leaflets which are deeply and intricately cut into toothed lobes, giving them a lacy appearance.

The dense and hairy inflorescence is a one-sided curving or coiling cyme of bell-shaped flowers in shades of blue and lavender.

[3] Phacelia tanacetifolia is native to the Southwestern United States and northwestern Mexico.

[7] It is a good insectary plant, attracting pollinators such as bumblebees and honey bees.
