Meadow phlox (phlox maculate) – They attract butterflies and hummingbirds with tubular purple flowers that appear in late summer and autumn. It is fairly resistant to powdery mildew, and it prefers damp conditions given its natural habitat of damp meadows and riverbanks of eastern North America. Full sun to light shade. Zones 3-8.
Lyreleaf sage (salvia Lyrate) – The lavender-blue, late-spring flowers of this plant draw bees and butterflies. Adaptable to wet or drier soils, this salvia species hails from eastern and central portions of the United States. Full sun. Zones 5-8.
Calico aster (symphyotrichum lateriflorum) – A late bloomer, calico aster keeps the garden flowering well into the fall when its small daisy-like blossoms continue to feed native bees. It can tolerate periodic flooding. Full sun to part shade. Zones 4-8.
Prairie dropseed (sporobolus heterolepis) – This warm-season ornamental grass adds color from late summer through the fall, thanks to its pinkish-brown flowerheads and golden-brown foliage. Left standing in the fall, it can shelter birds and beneficial insects over the winter. Zones 3-9.
Yellow wild indigo (baptisia tinctoria) – Drought-tolerant yellow wild indigo hosts the larvae of several butterfly species. Its late-spring flowers, summer seed pods, and rounded foliage are similar to those of the related blue false indigo (b. australis), but it blooms yellow. Full sun to part shade. Zones 3-9.
