Kaweah River Phacelia
Phacelia egena
About Kaweah River Phacelia (Phacelia egena) Nurseries Show All Photos Phacelia egena is a species of phacelia known by the common name Kaweah River phacelia. It is native to much of California, from the Transverse Ranges to the northern mountains and into Oregon; it also occurs in Arizona. It grows in many types of habitat. It is a herb producing a hairy, erect stem up to about 60 centimeters in maximum height. Most of the lance-shaped leaves are located low on stem, the largest over 20 centimeters long and divided into many leaflets. Leaves higher on the stem are much smaller and undivided. The flower cluster is a one-sided curving or coiling cyme of several bell-shaped flowers. The flower is just under a centimeter long and is white to cream in color with five protruding white stamens.
