Food-forest layered edible

A vertically stacked edible polyculture: nut-bearing canopy, fruit-bearing understory, berry shrub layer, herbaceous layer, and groundcover for temperate eastern North America.
Use this for larger sites (50ft+ width) where you want to harvest food at every vertical layer. Canopy + understory go in first; lower layers fill in as the canopy matures.
Layout notes
Plant shagbark hickory as the canopy anchor - long-lived (200-300+ years), edible nuts, Tallamy keystone genus.
Pawpaw + serviceberry are the understory layer - both fruit in shade as the hickory matures; plant 3+ pawpaws for better pollination and fruit set.
Highbush blueberry + allegheny blackberry are the shrub layer - keep blueberry in acidic pockets, blackberry contained (suckering thicket-former).
Chives + parsley anchor the herbaceous layer; parsley hosts black swallowtail.
Wild strawberry is the groundcover layer - spreads via runners under the rest.

Shagbark hickory (Carya ovata) as a mature tree in open lawn, showing the upright single trunk and irregular, rounded crown.
Carya ovata
Shagbark hickory
A native deciduous canopy tree of eastern North American forests with the most distinctive bark of any temperate tree - long curling shaggy plates that peel away from the trunk in vertical strips. Edible nuts (one of the few hickories with sweet kernels rather than bitter). Slow-growing + long-lived (200-300+ years). Among Tallamy's keystone genera - Carya hosts hundreds of Lepidoptera species.

Pawpaw (Asimina triloba) - a mature multi-stemmed understory tree in full summer leaf, showing its broad, rounded, suckering crown of large drooping leaves.
Asimina triloba
Pawpaw
A small native understory tree of eastern North American forests producing the largest native fruit on the continent - a banana-custard-flavored tropical-tasting drupe in late summer. The canonical larval host for zebra swallowtail (Protographium marcellus, an Annonaceae specialist) per NC State; without pawpaw colonies the butterfly cannot reproduce. Self-incompatible - two genetically distinct trees are required for fruit set. Fly-and-beetle-pollinated via fetid maroon spring flowers.

Allegheny blackberry (Rubus allegheniensis) showing arching thorny canes + ripe black berry clusters.
Rubus allegheniensis
Allegheny blackberry
A native eastern + central North American thicket-forming shrub producing arching thorny canes + clusters of large sweet black berries in mid-to-late summer. Among the most important wildlife fruit producers in eastern forests - birds, mammals, + insects all depend on the fruit. Like raspberry, biennial-caned (primocane year 1, fruits in year 2 as floricane, then dies back). Spreads via root suckers + tip-rooting cane tips; manage with annual pruning.

Allium schoenoprasum
Chives
A clumping perennial onion-relative forming dense grass-like tufts of hollow tubular leaves + globular lavender-pink flowerheads in late spring. Edible leaves + flowers; among the easiest perennial vegetables for beginners. Globular flowerheads are major early-season nectar sources for honey bees + native bees.

Parsley (Petroselinum crispum) showing flat green tripinnate leaves of the Italian flat-leaf type.
Petroselinum crispum
Parsley
A biennial Mediterranean herb in the carrot family (Apiaceae) grown as an annual for its leaves. The garden 'parsley worm' - caterpillar of the black swallowtail butterfly (Papilio polyxenes) - feeds exclusively on Apiaceae foliage; planting parsley is among the simplest ways to host a multi-year swallowtail population. Flat-leaf (Italian) selections have stronger flavor than curly selections.

Wild strawberry (Fragaria virginiana) showing trifoliate leaves + white five-petaled flower + small red berries.
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.
