About Phacelia grandiflora (Benth.) A.Gray
Phacelia grandiflora (Benth.) A.Gray is an annual herb with an erect stem that may be either branching or unbranched, reaching a maximum height of one meter. The entire plant is glandular, and covered with a mix of soft and stiff hairs. Its leaves can grow up to 15 centimeters long, with toothed, rounded or oval leaf blades that grow on long petioles. The plant produces a large, hairy, glandular inflorescence: a one-sided curving or coiling cyme that holds many widely bell-shaped flowers. Each individual flower is up to 2.5 centimeters long, and ranges in color from purple to blue, usually with a paler throat. There are reports that the glandular hairs covering the stems, flowers, and leaves of this species secrete oil droplets that can cause an unpleasant skin rash (contact dermatitis) in some people.
