This is such a cool plant. A super-silvery, compact but lanky shrub native to sandy areas of the U.S. Gulf coast. The leaves are certainly unexciting, shapewise, as they resemble little bluish-silver grains of rice, but the overall habit of the plant is charming. It's kind of like a natural bonsai; a small, gnarled blue juniper or conifer of some sort, to be exact. Mine flowers prolifically and has a wonderful smell, unlike the nasty smell of rosemary. And it relishes heat, unlike lavender. Just give it a fairly sandy soil mix in full sun and forget about it.

Today I read that it secretes monoterpenes, which are chemicals that inhibit growth of neighboring plants. (Some coral reef poylps do basically this same thing, probably with different chemicals, to prevent other... read more

False Rosemary or Short-leaved Rosemary is native to the fields, dunes and scrub and scrubby areas and sites scattered from central and south-central Florida northwestward through the Panhandle to Alabama and Mississppi in scattered areas. It is a shrubby wildflower that looks similar to Largeflower False Rosemary (see my comment on it), which is endemic to rare Florida Scrub, dunes and open, sandy, sunny scrubby sites and sand pine scrub on the east coast of Florida; however, Largeflower False Rosemary is usually not as tall as this species in shrubby habit although it, too, is shrubby and scrubby. This species is also not as spreading as Largeflower False Rosemary.
