Amsonia tabernaemontana
Eastern bluestar is an elegant, low-maintenance perennial with willow-like leaves and ice-blue, star-shaped flowers in loose clusters in May and June. The narrow foliage turns a stunning golden yellow in autumn, making the plant decorative across two seasons. Over the years it forms a sturdy, vase-shaped silhouette.
Plant in full sun or partial shade in well-drained soil. Once established, the plant is very drought-tolerant. Tolerates a wide range of soil types. No feeding needed. Virtually disease-free and not favoured by deer or rabbits.
Cut the plant back by a third after flowering if you prefer a more compact form. Leave the autumn foliage for the golden fall colour display. Cut dead foliage to the ground in early spring.
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.
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.
Penstemon digitalis
Foxglove beardtongue is a graceful North American native perennial with striking clusters of white, tubular flowers on elegant upright stems in June and July. The blooms attract a wide range of pollinators. The dark green foliage often has a reddish flush, especially in spring. An excellent choice for naturalistic plantings and prairie gardens.
