Silene regia

Royal Catchfly

General Information

Royal Catchfly is a slow -growing, clump-forming, herbaceous perennial.

Royal Catchfly is typically found in openings in upland forests, savannas, scrubby barrens, and open areas along roadsides and railroads. Royal Catchfly prefers dry to medium, well-drained soil and full sun to part shade. It does best in sandy or gravelly soil, as excellent drainage is essential.

Royal Catchfly has showy scarlet flowers and blooms around July.

Plants in the Catchfly family (Silene) have sticky hairs that discourage ants and other insects from eating the plant. Red is an uncommon color among prairie plants because many pollinating insects (e.g., bees) are insensitive to this range of the light spectrum (bees see as black).
