Ocimum basilicum
Genovese basil
A tender warm-season culinary herb native to tropical Africa and Asia; grown as an annual in most US climates for fragrant edible leaves and as a kitchen-garden staple. Sweet basil is the species behind Genovese, Thai, and most ornamental purple basils.

Melissa officinalis
Lemon balm
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.

Perilla frutescens (shiso) growing in a field in Gimpo, South Korea, showing the upright habit, square stems, and broad serrated leaves
Perilla frutescens
Shiso
Shiso is a fast-growing Asian culinary herb in the mint family (Lamiaceae), native across a wide arc from the Himalayas through China, Japan, and Korea to Southeast Asia (Wikipedia; GBIF). In temperate gardens it is grown as a tender annual reaching 24 to 35 inches, prized for its aromatic, serrated leaves used in Japanese, Korean, and Chinese cooking. The honest catch is its aggressive self-seeding: shiso sets abundant seed in late summer and is designated a weed in parts of the United States, so deadheading before seed set is essential unless you want a permanent colony - and all parts are toxic to grazing livestock (perilla ketone).

Cowpea (Vigna unguiculata) - pale-lilac standard petal with a deep purple-violet keel and yellow-green throat (the characteristic cowpea pea flower), long, slender, hairy green developing pod typical of the cowpea legume, trifoliate cowpea leaves on the living twining plant.
Vigna unguiculata
Cowpea
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.

Peppermint (Mentha × piperita) flowering shoot with a terminal spike of small two-lipped pale-pink flowers above opposite pairs of toothed leaves on a reddish square stem.
Mentha × piperita
Peppermint
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).

Bambara groundnut (Vigna subterranea) - low, ground-hugging clumped habit of a warm-season annual legume growing in a cultivated field row, compound (pinnate/trifoliate-type) green leaves on short, creeping/clustered stems radiating from the crown, crop planted in bare red-earth tilled soil with no aerial pods, consistent with the underground-fruiting groundnut growth pattern.
Vigna subterranea
Bambara groundnut
A low, ground-hugging warm-season annual legume domesticated in West Africa (around present-day Mali and Nigeria) and grown across the continent as a hardy indigenous pulse (GBIF). Trifoliate leaves rise on short, creeping stems, and after the tiny flowers are pollinated their stalks bend down and push the developing pods into the soil, so the crop ripens UNDERGROUND like a peanut. The round, hard seeds are remarkably rich in both protein and carbohydrate, making bambara groundnut a near-complete food and a staple where harsher conditions defeat other beans. It is famously DROUGHT-tolerant and productive on hot, poor, sandy soils, fixing its own nitrogen, but it is a FROST-TENDER, warm-season annual that needs a long, warm season for the underground pods to fill. RHS lists it as a tender, drought-tolerant warm-season annual pulse for full sun, its pods ripening underground (RHS). Outside the tropics it is grown as a summer annual, sown after the last frost once the soil is warm.
