Field bindweed

Broadleaf plantain is the broad-leaved, ground-hugging weed of lawns, paths, driveways, and roadsides across North America - and, honestly, an introduced Eurasian species, not a native. It forms a flat basal rosette of broad, strongly ribbed oval leaves that presses tight to the ground, sending up slender, erect, rat-tail flower spikes through summer. Its tie to human disturbance runs so deep that some Indigenous peoples called it 'white man's footprint,' because it followed colonists wherever soil was trodden bare. Despite the weedy reputation it is genuinely undervalued for habitat: the wind-pollinated spikes are heavy pollen sources, the ripe seed feeds finches and other small birds, and it is a documented larval host for the common buckeye butterfly. The young leaves are edible cooked or in salad, with a long medicinal and poultice history.

An Old World cottage-garden annual grown for daisy- to chrysanthemum-like flowerheads (3 to 4 inches across) in bright yellow through deep orange, often with a contrasting darker center disk. In cool climates it blooms over a long summer-to-fall window; in hot summers it tends to languish and may need a midseason cutback to rebloom. The somewhat bitter flowers and lance-shaped aromatic leaves are edible, and the petals lend color to soups, rice, and baked goods.

A fast, fine-textured cool-season culinary annual in the carrot family (Apiaceae), native to the Middle East, Russia, and the Caucasus and now grown worldwide. NC State Extension describes an erect, spreading plant about 12 to 24 inches tall with light green, feathery, finely divided (tripinnate) leaves - like a more delicate parsley - and a mild aniseed scent. Small white five-petaled flowers open in saucer-shaped umbels 1 to 2 inches across in spring and summer. It is generally grown as an annual (occasionally biennial in milder areas), prefers cool weather in moist, well-drained soil, and is a classic component of French fines herbes, prized for a delicate flavor best used fresh.

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).

Society garlic (Tulbaghia violacea) is a clump-forming perennial herb from South Africa grown for its long season of small, star-shaped lilac-pink flowers, carried in airy umbels on slender stems well above narrow, grassy, grey-green leaves from late spring into autumn. The foliage is garlic-scented, and the leaves and flowers are edible, used like garlic chives in South African cooking - the friendly name comes from its milder, more sociable garlic breath. It is an easy, drought-tolerant, long-flowering choice for sunny borders, edging, and containers, and a reliable bee and butterfly plant. Native to the Cape provinces and KwaZulu-Natal, it is reasonably hardy (to about USDA zone 7 with sharp drainage) but can be cut back or lost in a hard winter, and the garlic scent is reputed to deter some insect pests and even moles. RHS gives Tulbaghia violacea (and the cultivar 'Silver Lace') its Award of Garden Merit and rates it half-hardy (H3).

A tender perennial herb in the aster family (Asteraceae), grown for its remarkably sweet leaves - per the Missouri Botanical Garden PlantFinder the foliage contains glucoside compounds and tastes notably sweeter than sugar with no calories, which is why it is also called sweetleaf. Native to Brazil and Paraguay, it forms weak, floppy stems to 12 to 24 inches tall clothed in oblong, toothed leaves, with small showy white flowers in July and August. Winter hardy only in USDA zones 10-11; across most of North America it is grown as an annual or overwintered indoors, and leaves are best harvested before flowering.
