Scabiosa 'Butterfly Blue' is a compact, hardy perennial (12–18 inches tall) renowned for producing lavender-blue, 2-inch "pincushion" flowers from spring until frost. Ideal for borders and containers, it thrives in full sun and well-drained soil, attracting pollinators like bees and butterflies while resisting deer.
