Florida skullcap - Scutellaria floridana





Florida skullcap (Scutellaria floridana) is an exceedingly rare plant, endemic to Florida and only vouchered from Bay, Franklin, Gulf, and Liberty Counties in the central Gulf Coast side of the Panhandle.  It is listed as a federally threatened species.

There is limited information available for this species and I've had no personal experience myself. The above wonderful photos were taken by Floyd Griffith and used with permission. Florida skullcap is a perennial species that dies back to the ground in winter; reemerging again in early spring.  It occurs in moist, fire-dependent plant communities that include moist flatwoods, wet prairies and savannas.  It is reported that flowering does not occur in areas where fire is absent for more than 3 years.  This fire dependency may account for some of its rarity.

Plants reach a mature height of 12-15 inches by late spring to summer.  As for most mints, the stems are square. The short linear leaves occur as whorls along the main stem(s). Each is often tipped in red.  Flowers are typical in structure to the genus - the upper petals form a "helmet" above the broad lower lip.  Flowers occur up the top of each stem and emege from the axils of the upper leaves. They are produced from May to June. Each is a rich purple in color with a white patch on the inside of the lower lip and covered by soft white "hairs".  

Limited research reports that they are primarily pollinated by megachilid bees. Although skullcaps in general are wonderful additions to a wildflower planting in a home landscape, this is not one of those species. It's restricted habitat requirements make it unsuitable for most locations. Therefore, it is one of those wonderful wildflowers, restricted solely to our state, that should simply be admired for what it is.
