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 warm-season annual legume domesticated in sub-Saharan Africa (GBIF) and now grown throughout the warm world, cowpea is the black-eyed pea, southern pea, and cowpea of countless kitchens — a protein-rich African staple grown for both its young leaves and its seeds. The bushy or twining plants carry trifoliate leaves, pale lilac-to-white pea flowers, and long slender pods packed with seeds (often the familiar pale seed with a black eye). HONEST CLIMATE NOTE: this is a FROST-TENDER, warm-season ANNUAL for full sun. It is notably drought-tolerant and thrives in heat and poor soil, fixing its own nitrogen from the air, so it does not want rich nitrogen feeding — too much nitrogen gives you leaves instead of pods. Sow it after the last frost once the soil is warm and let it run through a long, hot summer; outside the tropics it is grown purely as a summer annual. The dried seeds are cooked like any bean and the young leaves are eaten as a cooked green. It is bee-pollinated but largely self-pollinating, so a single plant still sets a crop.

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.

The classic lawn daisy: a low, rosette-forming perennial with spoon-shaped leaves and white, often pink-tipped ray flowers around a yellow disc on short stems, blooming from spring into autumn. The flowers close at night and in rain — the old "day's eye" — and double cool-season bedding forms such as "Pomponette" and "Habanera" are widely grown. Often written off as a lawn weed, it is in fact a tough, charming, child's-favourite groundcover that flowers for months, thrives in mown grass because it keeps its blooms low, and offers easy early-season nectar and pollen. The flowers and young leaves are edible.

An aromatic annual herb of the daisy family (Asteraceae), grown for its small daisy-like flowers — 10-20 petal-like white rays surrounding a showy, bright-yellow domed center disk — borne June to August over finely divided, feathery, double-pinnate foliage. Native to Europe and western Asia, it reaches 1 to 2 feet tall and is most often grown in herb gardens to harvest its fragrant flowers, which are the chamomile used in most commercial chamomile tea because the species is sweeter and less bitter than Roman chamomile (Missouri Botanical Garden PlantFinder, which lists it under the synonym Matricaria recutita).
