Phlox 'Opalescence' is the flagship variety of the LUMINARYâ„¢ Collection and the gold standard of powdery mildew resistance. In an extensive mildew trial, this was the very best variety to display resistance. Light pink flowers have dark pink eyes and are produced over dark green leaves; the darkest green in the phlox trials at Walters Gardens.
Phlox needs rich, well drained soil that does not dry out to look its best. It is a heavy feeder so a fall mulch with compost is beneficial to keep up the organic level in the soil. This variety has the best mildew resistance to date but all phlox benefit from good air circulation.
