Garden sorrel
Rumex acetosa
A herbaceous perennial of the buckwheat family (Polygonaceae) grown as a culinary herb for its basal clusters of arrowhead-shaped leaves, which carry a tangy, acidic, sour-lemony flavor used in salads, soups, omelets, and sauces. Native to northern temperate regions, it reaches about 2 feet tall and sends up long, spike-like terminal clusters of greenish flowers that turn reddish with age in summer. Per the Missouri Botanical Garden PlantFinder, it self-seeds and spreads in the garden, and flowers should be removed promptly to keep new leaf growth coming; younger leaves taste best.

Borago officinalis
Borage
A rough, sprawling Mediterranean annual grown for showy, open racemes of drooping, star-shaped bright blue flowers in summer. Branched stems and wrinkled, dull gray-green leaves are clad in bristly hairs and carry the taste and fragrance of cucumber. Easy in poor, dry soils, drought-tolerant, a magnet for bees, and a self-seeder that returns to the garden year after year.
Anethum graveolens
Dill
A fast annual culinary herb grown for both its aromatic, feathery blue-green foliage and its pungent seeds. Stiff hollow stems rise 3-5 feet and carry large, flattened compound umbels of tiny yellow flowers in late summer. Native to Asia Minor and the Mediterranean, dill has naturalized across parts of North America. The showy umbels draw bees, wasps, lacewings, hover flies, and other beneficial insects, and the lacy foliage is a classic larval host for the black swallowtail butterfly.
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.
Mentha spicata
Spearmint
A vigorous spreading perennial mint forming dense colonies via aggressive underground rhizomes. Leaves are the canonical 'mint' flavor (toothpaste, gum, mojitos, lamb dishes). NC State + every herb reference flags Mentha species as highly invasive in garden beds — container-only siting is the standard recommendation. Small pink-to-white summer flowers worked heavily by bees + small pollinators.
Matricaria chamomilla
German chamomile
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).
