Shaggy purple blooms, buzzing with bees

Description
Monarda didyma 'Balmy Purple' is a compact, dwarf bee balm producing shaggy, tufted heads of vivid purple flowers, each ringed by a whorl of colourful bracts and quite unlike anything else in the summer border. Flowering from early summer over aromatic dark green leaves that release a fresh, minty scent when brushed, it draws bees and butterflies in numbers. Bred as part of the Balmy series for its dwarf habit and much improved mildew resistance, it is far easier to live with than older monardas, and small enough for a container or the front of a border.

Planting & care
Help it thrive
Planting guide
Plant in spring or early autumn into moderately fertile, humus-rich, moist but well-drained soil in full sun or partial shade. It is not fussy about soil type provided it stays reliably moist, so improve light ground with plenty of compost and mulch to hold moisture. Give it space and air movement around the plant, which helps keep mildew at bay. Water in well and space around 25 to 30cm apart.
Care tips
Keep the soil moist through summer and never let it dry out, as drought stress is what brings on powdery mildew. Water at the base rather than over the leaves. Deadhead spent flowers regularly to keep the display going into autumn. Cut back after flowering or in early spring, and divide clumps every three years or so to keep them vigorous, as monardas spread steadily and can lose their centres.
