Sometimes omitted from flower books, Phacelia heterophylla is none-the-less a fairly common plant in our area.  It is easily overlooked because of its overall "just green" look.  A careful examination will show it to be as fascinating as other members of the Waterleaf Family with their protruding stamens and their often coiled, scorpion-like tails.  All parts of the plant are very hairy.  Plant height ranges from five to thirty inches.

"Heterophylla" is Greek for "different leaves", referring to the varying shapes and sizes of the plant's leaves.

Phacelia heterophylla was first collected by Meriwether Lewis on the Lewis and Clark Expedition and was named by Frederick Pursh in his Flora Americana in 1814.

Phacelia heterophylla flower heads first appear as tight green spheres,

white flowers open from the sphere,

and eventually the sphere opens into an arching scorpion tail and flowers fade to rusts.
