Ramps
Allium tricoccum
A spring-ephemeral wild leek of eastern North America’s rich, moist deciduous woods — the earliest edible green to carpet the forest floor each spring with broad, smooth, leek-scented basal leaves. The foliage withers by early summer, when a leafless scape rises to lift a rounded umbel of small white flowers above the leaf litter. Prized but heavily over-harvested as a foraged food, so it is best grown deliberately in deep woodland shade.

Fragaria virginiana
Wild strawberry
A low-growing native eastern North American perennial groundcover producing small intensely-flavored red berries in early summer + white five-petaled flowers in spring. The genetic parent (with F. chiloensis) of the modern cultivated strawberry (F. ×ananassa). Berries smaller than cultivated but exceptional flavor. Spreads via runners (stolons); makes excellent edible groundcover under fruit trees.
Matteuccia struthiopteris
Ostrich fern
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.
Sanguinaria canadensis
Bloodroot
A native eastern North American spring ephemeral wildflower with pristine white 8-12-petaled flowers in early spring (often the first major forest-floor wildflower of the year) wrapped by a single rounded glaucous leaf. Disappears by midsummer to underground rhizomes. The red rhizome sap was historically used by Indigenous peoples as a dye and ceremonial paint.
Polystichum acrostichoides
Christmas fern
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.
Viola sororia
Common blue violet
A low, clump-forming native woodland violet of eastern North America, grown for its early spring blue-to-purple flowers with conspicuous white throats held over glossy, heart-shaped leaves. It does not run, but self-seeds freely — to the point of being weedy in rich, moist ground. A larval host for fritillary butterflies and a nectar source for early bees and butterflies; the leaves are high in vitamins A and C.
Iris cristata
Dwarf crested iris
A diminutive native woodland iris forming spreading mats of low sword-shaped foliage topped briefly in spring by delicate light-blue flowers with bold yellow + white "crests" running down each fall. One of the most charming native perennials for partly shaded sites. Among the smallest native irises (6-9" tall) — works beautifully as a groundcover under deciduous shrubs + along path edges. ALL parts toxic (typical iris caveat).
