A bushy, lemon-scented herbaceous perennial of the mint family, grown for its wrinkled, ovate medium-green leaves that crush to a bright citrus fragrance. Tiny two-lipped white-to-pale-yellow flowers appear in the leaf axils through summer and draw bees. Native to southern Europe, it has escaped gardens and naturalized across much of the U.S.; frequent pruning keeps it leafy, curbs self-seeding, and produces the most fragrant new growth.

A fast, erect cool-season annual in the mustard family (Brassicaceae), introduced to all of North America from Eurasia and grown widely as a leafy vegetable. NC State Extension describes a rapid-growing plant about 1-1.5 feet tall and wide with large (over 6 inches) leaves — lobed lower leaves and shorter-stalked upper leaves, smooth with a whitish bloom and sometimes purple veins or fully purple coloring. It does best in the cool of fall and spring and bolts in summer heat, throwing up terminal clusters of small four-petaled yellow flowers and developing a strong, spicy flavor. The leaves, seeds, flowers, and stems are all edible raw or cooked, making it a productive, peppery green for the edible garden.

A tender, tuberous-rooted morning-glory relative native to tropical America and cultivated for its starchy edible storage roots for over 2,000 years. Trailing stems mound only about 9 inches tall but sprawl 8 to 10 feet wide, rooting at the nodes, with heart-shaped to palmately-lobed leaves. The species occasionally bears pale-pink-to-violet trumpet flowers, though most cultivars rarely bloom. Winter hardy only to USDA Zones 9-11, it is grown as a warm-season annual everywhere colder.

A rhizomatous, upright herbaceous perennial of the mint family, most commonly grown as a culinary or medicinal herb and as a ground cover. A natural hybrid of watermint (Mentha aquatica) and spearmint (Mentha spicata), it carries fragrant rounded-to-lance-shaped toothed leaves on square stems and showy pink flower spikes in mid- to late summer. Native to Europe, it spreads aggressively by rhizomes into an attractive ground cover and rarely sets seed, so it is propagated vegetatively and is best confined by a soil barrier (Missouri Botanical Garden PlantFinder).

A tender perennial herb in the aster family (Asteraceae), grown for its remarkably sweet leaves — per the Missouri Botanical Garden PlantFinder the foliage contains glucoside compounds and tastes notably sweeter than sugar with no calories, which is why it is also called sweetleaf. Native to Brazil and Paraguay, it forms weak, floppy stems to 1-2 feet tall clothed in oblong, toothed leaves, with small showy white flowers in July and August. Winter hardy only in USDA zones 10-11; across most of North America it is grown as an annual or overwintered indoors, and leaves are best harvested before flowering.

A productive cool-season edible Brassica (a wild-cabbage cultivar in the Acephala / non-heading group, alongside collards). Upright blue-green strap-shaped leaves with strong kitchen-garden value and ornamental texture; grown as a cool-season annual or short-lived biennial.

A compact edible collection for containers, patios, and near-door harvesting.
