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).

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 low woody herb for sunny edges, between pavers, and herb-garden borders with pollinator-friendly summer flowers.

A low, drought-loving Mediterranean herb grown for its woolly silver-grey rosettes of soft, felted leaves and its stiff summer spikes of small, soft-yellow flowers cupped in densely woolly bracts - the plant known as Greek mountain tea or ironwort. It is a tough alpine and rock-garden subject that wants hot, dry, very sharply drained ground and full sun, and rots in wet or rich soil; it is only borderline hardy. POWO (Kew) records Sideritis syriaca as native to the eastern Mediterranean - Crete, the Levant, and Türkiye. The dried leaves and flower spikes make the traditional caffeine-free Greek herbal infusion long valued as a folk remedy for colds and coughs, so it is parts-edible as a tea but is grown as a herb rather than a food crop. The soft-yellow summer spikes are a good bee plant.

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 fast, bushy annual culinary herb in the mint family (Lamiaceae), native from southeastern Europe to western Asia. NC State Extension describes an erect, multi-stemmed plant about 18 inches tall and 1 to 3 feet wide, with linear, gland-dotted, aromatic dark-green leaves and small lilac, pink, or white summer flowers. It grows rapidly - harvestable within a couple of months of sowing - and is prized for its mild, slightly peppery flavor. Grown as a warm-season annual, it wants full sun and sharp drainage and does poorly in damp soil or shade.
