Phlox carolina ssp. carolina

3 Photos


Phlox carolina ssp. carolina was not an exceptionally vigorous accession in our garden. The plants were small when initially planted and did not bulk up very much. Leaf spot was a problem with several other types of Carolina phlox; however, it was much less so with this subspecies. The cultivar ‘Kim’ also belongs to this subspecies, and is a much more vigorous plant and an overall better selection for the garden. Like other accessions of Carolina phlox, powdery mildew was never a concern.
