About Imbricate Phacelia (Phacelia imbricata) 4 Nurseries Carry This Plant Phacelia imbricata is a species in the Boraginaceae (Fort-me-not) family known by the common name Imbricate Phacelia. It is native to much of California and Baja California, where it can be found in varied habitat in mountains, valleys, and coastline. It is a perennial herb growing decumbent or erect to a maximum height exceeding one meter. It is hairy and coated in stiff hairs. The leaves may be up to 15 centimeters long and are divided into several leaflets. The flower cluster is a one-sided curving or coiling cyme of many bell-shaped flowers. The flower is roughly half a centimeter long and white to pale purple in color. It is almost always grown from seed. There are four recognized varieties with differing geographic ranges.

It should be noted that there are a very large number of species in the genus Phacelia. Most are annuals. Gardeners should look for species appropriate to their area and garden conditions.
