Monarda didyma
Bee balm is a striking perennial with aromatic foliage and crown-like flowers in fiery red, pink or purple that appear in whorls around the stem in July and August. The blooms are a magnet for bees, butterflies and hummingbirds. The aromatic leaves release a bergamot scent when rubbed between the fingers.
Plant in full sun to partial shade in moist, fertile soil. Ensure good air circulation to prevent mildew. Keep the soil evenly moist. Mulch around the base to retain moisture. Divide the plant every three years to maintain vigour.
After the first flush of flowers, deadhead — a second, lighter bloom often follows. Cut back dead foliage to the ground in autumn. Thin dense clumps in spring for better air circulation.
Echinacea purpurea
Purple Coneflower is a sturdy perennial with distinctive pink-purple petals surrounding an orange-brown cone. The flowers appear from July to September and are a magnet for butterflies and bees. In autumn and winter, the seed heads attract goldfinches and other seed-eating birds.
Phlox paniculata
Garden Phlox is a stately border plant with large, dome-shaped flower clusters in pink, purple, or white. The blooms release a sweet fragrance and appear from July to September. Phlox is indispensable in the classic cottage garden.
Baptisia australis
Blue wild indigo is a stately, long-lived perennial with blue-green trifoliate leaves and striking racemes of indigo-blue, lupin-like flowers in May and June. After flowering, decorative inflated dark seed pods appear that remain attractive into winter. The plant forms a sturdy, shrub-like clump that grows larger and more impressive each year.
