I can hear the chants from the Tennessee volunteer faithful, as they begin humming the State song of Tennessee. Instead, we are referring to one of their finest ornamental plants from the Cumberland Plateau region (TN, KY, and SC), the Federally Threatened Conradina verticillata ‘Rocky Top’, commonly referred to as Cumberland rosemary. For the last week or so, our plant of this amazing clonal selection of the woody native mint has been in full splendor. In the wild, this occurs on gravelly stream banks, that flood seasonally, but dry out in summer. If you can site this correctly, the stunning floral show atop the needle-like, minty-fragranced leaves will be one of the most stunning plants in the spring garden.
The US Fish & Wildlife Service map for this only has TN and KY (no SC):

We thought it odd also the the Center for Plant Conservation lists it also as being in SC.
