Borage

Borago officinalis
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.

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.

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).

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.

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.

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).
