About this plant

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.

  • Why we like it

    'Balmy Purple' brings all the character of a classic bee balm on a plant small enough for a pot or a border edge. The shaggy, tufted purple flowers are unlike anything else in the summer garden and pull in bees and butterflies from across the plot, while the foliage releases a fresh, minty scent whenever you brush past. It also holds up better against the powdery mildew that plagues older monardas, which makes it a much easier plant to live with.

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.
