Royal Catchfly is similar to Fire Pink (Silene virginica), but is taller and blooms later in the season (June-August) with brilliant two-inch wide red flowers that provide nectar for butterflies and hummingbirds. The flower, which is sticky, gives the plant its common name. Royal Catchfly, unlike Fire Pink, likes being planted with companion plants such as Little Bluestem, Prairie Dropseed or Missouri Black-eyed Susans, which help support it. It can be found naturally occurring on savannahs and is a relatively short-lived plant that self-sows.
