Catchfly (Silene armeria), also known as Sweet William Catchfly, is a charming annual wildflower prized for its clusters of vivid pink to rose-colored blooms. The star-shaped flowers appear in dense clusters above blue-green foliage, creating a bright, eye-catching display from late spring through summer.
Growing 12–24 inches tall, Catchfly is easy to grow and thrives in sunny garden beds, borders, cottage gardens, and wildflower meadows. The blooms attract bees, butterflies, and other beneficial pollinators, making it an excellent addition to pollinator-friendly plantings.
The plant gets its name from the slightly sticky stems, which were once believed to trap small insects. Fast-growing and low maintenance, Silene armeria often self-seeds lightly under favorable conditions.
