Rosemary
Salvia rosmarinus
A Mediterranean-native evergreen aromatic woody subshrub long known as Rosmarinus officinalis (reclassified to Salvia rosmarinus in 2017 based on molecular phylogenetics). Highly drought-tolerant once established; pale-blue spring flowers; foliage harvested year-round in mild climates as the canonical Mediterranean culinary herb. Borderline-hardy in zones below 7 — overwintered indoors or treated as annual outside zones 8-10.

Better fit for this place
For Chicago, IL, these are replacement suggestions: similar plants with a stronger hardiness fit now and/or in 2050.
Levisticum officinale
Lovage
A tall, somewhat imposing herbaceous perennial culinary herb grown for the celery-like flavor of its leaves, stems, roots, and seeds. Native to the eastern Mediterranean and reaching up to 6 feet in height, it carries small umbels of tiny, greenish-yellow flowers in spring above ternately compound, deeply divided, dark-green leaves that resemble flattened parsley or celery (Missouri Botanical Garden PlantFinder).

Aronia melanocarpa
Black chokeberry
A drought-and-flood-tolerant native shrub of eastern North America with brilliant three-season interest — spring white-pink flowers, glossy black antioxidant-rich late-summer berries, and brilliant wine-red fall foliage — plus an extraordinarily wide cold-hardiness range (USDA 3a-8b). The berries are astringent fresh but the basis of a small but growing commercial industry (juices, wines, jams, supplements) for their exceptionally high anthocyanin content. Spreads by suckers; site where colony formation is welcome.

Salvia officinalis
Garden sage
A Mediterranean evergreen subshrub with gray-green velvety foliage + lavender summer flowers. Among the most useful kitchen herbs + a strong nectar source for honey bees, native bumblebees, and solitary bees. Perennial in zones 4a-8b; longer-lived in well-drained alkaline soils.

Artemisia dracunculus 'Sativa'
French tarragon
French tarragon is the culinary clone of Artemisia dracunculus, grown for the pungent anise-like flavor and aroma of its narrow, glossy green leaves — the defining herb of béarnaise sauce and classic French fines herbes. It is a shrubby, rhizome-spreading perennial that rarely flowers and sets effectively sterile seed, so it is propagated only by cuttings or division rather than from seed. Unlike its wild parent species and the inferior Russian tarragon, this 'Sativa' selection holds the true tarragon flavor.

Calendula officinalis
Calendula (pot marigold)
An Old World cottage-garden annual grown for daisy- to chrysanthemum-like flowerheads (3-4 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.
Allium schoenoprasum
Chives
A clumping perennial onion-relative forming dense grass-like tufts of hollow tubular leaves + globular lavender-pink flowerheads in late spring. Edible leaves + flowers; among the easiest perennial vegetables for beginners. Globular flowerheads are major early-season nectar sources for honey bees + native bees.

Mediterranean drought-tolerant edible
A low-water edible palette of culinary herbs + a hardy grape for hot dry sunny sites. Mediterranean-origin plants thrive on neglect; their primary failure mode is overwatering, not underwatering.
