Shade & understory woodland
A full-shade woodland-floor community for deep shade beneath a closed canopy: an understory shrub, spreading groundcovers, spring ephemerals, and a large fern — eastern North American natives that expect low light and leaf-litter soil.
Use beneath a mature tree canopy or on the deeply shaded north side of a building, in soil enriched with leaf litter. The spring ephemerals do their work early then go dormant — pair them with the ferns and groundcover that hold the space all season.
Layout notes
Spicebush is the understory shrub layer — full-to-part shade, host to the spicebush swallowtail, with red drupes for birds.
Wild ginger is the deep-shade groundcover — a slow-spreading mat across the woodland floor.
Bloodroot and Virginia bluebells are the spring ephemerals — they bloom before the canopy leafs out, then go summer-dormant, so site them where the ferns fill the gap.
Mayapple forms colonial drifts from a single rhizome — give it room to run; only the ripe fruit is non-toxic, the rest of the plant is poisonous.
Ostrich fern is the large fern layer (3-5 ft) — it wants consistently moist shade and spreads by runners; foamflower carries the low near-evergreen groundcover between the rest.

Lindera benzoin
Northern spicebush
A native deciduous shrub of eastern North American bottomland forests, valued for early-spring greenish-yellow blooms, brilliant scarlet drupes on female plants, butter-yellow fall foliage, and its role as the canonical specialist host for spicebush swallowtail butterfly larvae. One of the most ecologically load-bearing native shrubs for partly shaded woodland and rain-garden plantings.
Asarum canadense
Wild ginger
A native eastern North American clump-forming deciduous perennial with heart-shaped foliage and hidden ground-level maroon flowers (pollinated by ground-dwelling beetles + flies). Forms dense colonies via rhizomes. Aromatic rhizome was historically used as a ginger substitute by Indigenous peoples + colonial settlers (true ginger is unrelated tropical Zingiber).
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.
Mertensia virginica
Virginia bluebells
A native spring ephemeral wildflower of eastern North American floodplain woodland understory producing pendulous pink-to-blue bell-shaped fragrant flowers above smooth blue-green foliage in April-May, then disappearing completely by midsummer as the foliage dies back to underground roots. Among the most beloved native woodland plants for shaded gardens; pair with later-emerging shade perennials to fill the post-dormancy gap.
Podophyllum peltatum
Mayapple
A native eastern North American spring ephemeral with distinctive umbrella-shaped leaves on paired stems, a single nodding white flower hidden beneath, and a single fleshy edible fruit when ripe. All other plant parts toxic; only fully ripe yellow fruit is edible. Forms extensive colonies via underground rhizomes in deciduous forest understory.
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.
Tiarella cordifolia
Foamflower
A native eastern North American semi-evergreen perennial with heart-shaped foliage and frothy white-to-pink spring flower spikes — among the most reliable native shade groundcovers for woodland gardens. Spreads by stolons in some forms; clumping in others (cultivars selected for both habits).
