Rudbeckia fulgida
Black-eyed Susan
A tough, bright perennial for sunny borders, pollinator patches, and late-summer color.
Echinacea purpurea
Purple coneflower
A drought-tolerant native perennial of the central and eastern United States with long summer bloom, strong pollinator value, and winter seedheads for birds.
Monarda didyma
Scarlet bee balm
A fragrant native perennial with red summer flowers that draw hummingbirds, bees, and butterflies.
Pycnanthemum muticum
Short-toothed mountain mint
A clump-forming aromatic native perennial of eastern North America, grown as much for its silvery floral bracts as its bloom — the upper leaves below each flower head turn a frosted, dusty-mint color in summer. Dense flat-topped clusters of tiny two-lipped pinkish-white flowers cover the plant from mid to late summer and are a magnet for bees and butterflies. Unlike the true mints (Mentha), it spreads only modestly by rhizome and is not invasive.
Monarda fistulosa
Wild bergamot
A widespread native perennial in the mint family with showy lavender flower heads through summer, distinctly more drought-tolerant than its cousin scarlet bee balm (Monarda didyma). Supports ruby-throated hummingbirds, hummingbird clearwing moths, three documented specialist bees, and provides stem-nesting bee shelter through winter.
Asclepias tuberosa
Butterfly weed
A clump-forming native milkweed with bright orange summer flowers, strong pollinator value, and tolerance for dry sunny sites.
