Silene regia, commonly called royal catchfly, is a Missouri native wildflower which occurs in dry, rocky soils in open woods, wood margins and prairies primarily in the Ozark region of the State. A clump-forming perennial which grows 3-4' tall. Small clusters of 5-petaled, scarlet red flowers (2" across) appear in summer. Sticky calyx can trap or "catch" small insects, hence the common name. Long, slender, often reclining stems. 10-20 pairs of downy, lance-shaped leaves (to 5" long). Similar to fire pink (Silene virginica), except royal catchfly is taller and blooms later, leaves are thicker and flower petals lack notches. Silene is in the same family as Lychnis and Dianthus.
Genus name comes from the Greek name for another plant (Viscaria), now applied to these common herbs.
Specific epithet means royal or princely.
No serious insect or disease problems. Taller plants may need some support.
Best in part shade areas of wildflower gardens, native plant gardens, woodland gardens or cottage gardens. Can also be grown in borders.
