Phlox paniculata Luminary® ‘Backlight’ is the bright white flowering showstopper in the Luminary® collection, which was bred to produce a prolific flowering tall Garden Phlox with exceptional color as well as disease resistance. From July to September, showy upright panicles of brilliant white flowers over dark green leaves attract various pollinators to the center of the perennial border or moonlight garden, where the glow of the moon illuminates the stark white petals and gives this upright perennial its namesake. This particular selection prefers full sun, but is tolerant of very light shade conditions, as well as high heat and humidity.
