Needless to say, this was the last photo I snapped on the trip because my phone died shortly after. But, I'm so glad I did because, otherwise, I wouldn't have realized that I had come across the most rare plant I've seen to date- sea rosemary (Argusia gnaphalodes). In fact, this is the only native Argusia species found in the states.
Sea rosemary can reach 6-feet tall with a 20-foot spread, which is how I found my plant. Extremely tolerant to salt and drought, sea rosemary also prefers full sun. I found this plant in a small opening on the edge of a remote island beach hidden among a patch of red mangroves. The succulent, silky tomentose leaves really stand out and the aromatic flowers, which flower intermittently throughout the year on this evergreen shrub, were in peak bloom. Today, conservation efforts for this dune stabilizing plant are increasing through cultivation.
According to The Institute for Regional Conservation: Florstic Inventory of South Florida Database, this plant has been recorded in Monroe County, which includes the island I found it on. Globally, this plant extends through the Caribbean and into South America - Florida being its northern most range.
