Low Phacelia
Phacelia humilis
About Low Phacelia (Phacelia humilis) 0 Nurseries Carry This Plant Phacelia humilis is a species of phacelia known by the common name low phacelia. It is native to the western United States from central Washington to central California, where it grows in mountain and foothill habitat. It is an annual herb with an erect stem growing up to 20 centimeters tall. It is hairy and coated in stiff hairs. The oval leaves are 1 to 4 centimeters long. The flower cluster is a one-sided curving or coiling cyme of bell-shaped purple flowers. Each flower is roughly half a centimeter long and surrounded by a calyx of sepals which are coated densely in long, straight, white hairs. Most instances of this plant are var. humilis. A second variety, var. dudleyi, is known only from the Sierra Nevada and adjacent Tehachapi Mountains of California.
