A spectacular tall vase-shaped native fern with broad upright sterile fronds (resembling ostrich plumes — hence the name) and distinctive contrasting fertile fronds that emerge brown + persistent through winter. The traditional edible fiddlehead source — young curled fronds harvested in early spring are sold seasonally as a delicacy. Spreads vigorously via rhizomes in moist soils; provides good groundcover-scale presence.

A native evergreen fern of eastern North America that holds leathery dark green fronds through winter and provides ground-level songbird cover — ideal for shaded woodland slopes and erosion-prone banks.

A dry-country wildflower of the Intermountain West whose narrow, scarlet, tubular flowers line a slender stalk that rises about 3 feet above a low rosette of glaucous blue-green leaves. The Lady Bird Johnson Wildflower Center documents it blooming red from May into August on dry, gravelly soils, and it is one of the classic hummingbird-pollinated penstemons. Deeply drought-tolerant once established — best on lean, well-drained ground where it is not over-watered.

A tall, tuber-forming perennial sunflower native to eastern North America — also called Jerusalem artichoke or sunroot — grown both for its 2-4 inch bright-yellow late-summer sunflowers and its knobby edible underground tubers. Rough-hairy stems rise 6-10 feet bearing ovate, serrate leaves on winged petioles. It spreads aggressively by rhizome and self-seeding to form colonies; Missouri Botanical Garden flatly calls it "weedy and invasive" and difficult to remove once planted.

A circumboreal evergreen groundcover with small white-pink urn-shaped flowers, glossy leathery leaves, and bright-red bear-edible berries. One of the most reliable native evergreen groundcovers for cold sandy sites; widely used in northern landscapes for slope stabilization + low-maintenance native plantings.

A native evergreen fern with leathery dark blue-green fronds in upright vase-shaped clumps. Among the most drought-tolerant native ferns — useful for drier-shade settings where most other ferns fail. The "marginal" name refers to sori (spore clusters) carried at the leaflet margins. Evergreen through winter in zones 5+; reliably long-lived (20-30+ years).
