Phacelia tanacetifolia is a species of phacelia known by the common names lacy phacelia, blue tansy or purple tansy.

Phacelia tanacetifolia is an annual herb that grows erect to a maximum height near 100 centimeters (39.37 inches) with none to a few branches. The wild form is glandular and coated in short stiff hairs. The leaves, 20–200 millimetres (0.8–7.9 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. Each flower is just under a centimeter long and has protruding whiskery stamens. The seeds are "negatively photoblastic", or photodormant, and will only germinate in darkness.
