A tall native eastern US perennial with deep purple-magenta flower clusters in late summer — among the most striking color in the native fall meadow palette. Tall and tolerant of wet feet; pairs visually with joe-pye weed + goldenrod for an iconic eastern wet-meadow trio.

A tall native perennial wildflower of moist meadows and woodland edges across eastern North America, producing large domed clusters of vanilla-scented pink-purple flowers in late summer — among the most reliable late-season nectar sources for monarchs, swallowtails, skippers, and native bees. Formerly classified as Eupatorium purpureum.

A native eastern + central North American wetland iris producing striking violet-blue flowers with yellow + white throat markings in late spring + early summer. Tolerates wet feet better than most irises — among the best perennials for rain gardens, stream edges, and pond margins. Long-lived; clumps slowly expand. ALL parts of the plant are toxic (irisin glycoside) — wildlife typically avoid it; humans + pets can experience GI distress + skin irritation from sap contact.

A short-lived native perennial of wet woodland edges, stream banks, and ditches across the Americas, named for the brilliant scarlet-red flowers that rise on erect, unbranched terminal spikes from mid-to-late summer. Each tubular, two-lipped bloom is shaped for the hummingbird tongue — the plant depends on ruby-throated hummingbirds for pollination because most insects cannot work the long flower tube. It demands constant moisture and tolerates brief flooding, but its foliage carries alkaloids that are very toxic to humans if eaten.

A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.

A native evergreen shrub of the eastern North American Appalachian + Piedmont understory producing extraordinary spring clusters of pink-to-white cup-shaped flowers with a unique spring-loaded pollination mechanism (anthers held under tension, triggered by visiting pollinators). State flower of Connecticut + Pennsylvania. Critically: NC State explicitly flags Kalmia as having HIGH-SEVERITY poison characteristics — all plant parts toxic to humans, dogs, cats, horses, and livestock; even honey from mountain-laurel nectar can poison humans ("mad honey").
