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 flavor teas. Creating captivating border displays, this Bee Balm variety is perfectly suited to the middle of the flower border. It enjoys above average resistance to powdery mildew
