Broadleaf plantain

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 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.

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 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.

A vigorous, semi-evergreen, clump- and colony-forming hardy geranium grown as one of the best groundcovers for dry shade under trees and shrubs. Its soft, deeply lobed, strongly aromatic leaves form a dense, weed-smothering carpet, many of them flushing red and bronze in autumn, and above the foliage rise loose clusters of magenta-pink (or white) flowers with prominent protruding stamens in late spring and early summer. It spreads steadily by thick surface rhizomes into a tough, low-maintenance, weed-proof mat that is easy to pull back and is not aggressively invasive. The aromatic foliage makes it markedly deer- and rabbit-resistant, and it is genuinely drought-tolerant once established. It is grown purely as an ornamental and is not a food plant.

Canada anemone (Anemone canadensis) is a vigorous, spreading native perennial of moist meadows, streambanks, and ditches across much of northern and central North America, grown for clean white cup-shaped flowers held over deeply cut, sharply toothed foliage in late spring and early summer. Be warned first: it spreads aggressively by underground rhizomes and can become a thug in a normal bed, running well beyond where you plant it and knitting into large colonies. That habit makes it an excellent plant for naturalizing a damp bank or filling a tough, contained spot, and a poor choice for a tidy mixed border where it will overrun quieter neighbors. Each flower carries five showy, petal-like white sepals around a boss of yellow stamens (the true petals are absent) on erect hairy stems to about 12 to 24 inches. It wants medium to wet soil in full sun to part shade and is hardy roughly from USDA zone 3 to 8.
