Nectar-rich, light purple flowers are produced continuously from spring to fall on tall spikes that butterflies, bees, and hummingbirds cannot seem to resist! Lavender Porterweed is a medium to large growing exceptionally full and vigorous Porterweed was once considered to be a purple form of the highly popular Coral Porterweed although we have learned that this is a sterile or nearly sterile hybrid cultivar.
