Earlier today, as I began to dig through pictures from my recent kayak trip to the lower Florida backcountry keys, I came across a cell phone photo that I almost forgot I even captured of a unique plant I came across on a small, remote Island. To give you an indication of how much this plant stuck out to me in a hidden, sandy corner of the island, I made the decision to turn on my cell phone and snap a photo, which was on its last leg and had outlasted my digital camera battery at that point. So, yes, the nerd in me was willing to jeopardize having the security of a cell phone on a kayaking trip in the middle of nowhere to have the opportunity to identify this plant.
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.
