Compact, Monarda 'Blue Moon' (Bee Balm) is a clump-forming perennial boasting lavender blue flowers, 2 in. across (5 cm), borne in dense, globular terminal heads. Blooming for weeks from mid to late summer, they rest upon a whorl of decorative purple bracts and attract scores of butterflies and hummingbirds. The showy blossoms rise on strong, well-branched stems, clad with aromatic, dark green leaves, which exude a mint fragrance when crushed, and are often used to flavour teas.
