A cool-season leafy green eaten raw or lightly cooked — among the most fundamental garden vegetables. Bolts (sends up flower stalks) + turns bitter in heat above 70°F per NC State; cool-spring + cool-fall windows are the productive growing periods in most North American climates. Four habit groups: head (iceberg, crisphead), loose-leaf, romaine (cos), and butterhead (Bibb, Boston).

A fast cool-season annual of the mustard family grown for its peppery, mustard-like salad greens — irregular, pinnately-lobed basal leaves in a low rosette, each with 4 to 10 small lateral lobes and a large terminal lobe (Missouri Botanical Garden). First cultivated by the ancient Greeks and Romans and still widely grown across Europe, it is best grown in the cooler spring and fall months rather than summer heat; leaves are harvested young and tender before they turn strong and bitter. Pale-yellow four-petalled flowers with dark brown or purple veins appear in corymbs if plants are left to bloom.

A fast, cool-season leafy annual grown for its tender, vitamin-rich basal rosette of leaves — an excellent source of vitamins A, B, and C plus iron and phosphorus per the Missouri Botanical Garden. Cultivated in Europe since the 1400s and probably native to western Asia, it crops best in the cool temperatures of spring and fall and bolts (sends up greenish-yellow flower spikes of no ornamental value) once summer heat arrives, after which the leaves deteriorate.

A tender warm-season culinary herb native to tropical Africa and Asia; grown as an annual in most US climates for fragrant edible leaves and as a kitchen-garden staple. Sweet basil is the species behind Genovese, Thai, and most ornamental purple basils.

A warm-weather annual of the carrot family grown in herb gardens for two distinct crops from one plant: the lacy, strong-scented foliage harvested young as cilantro, and the aromatic dried seed harvested as coriander. The plant bolts and flowers quickly in hot weather, throwing up showy white-to-pale-lavender umbels and a marked leaf dimorphism — broad scalloped lower leaves give way to fine, thread-like upper foliage on the flowering stems. Fast and easy from a direct sowing, it is best succession-planted for a steady leaf harvest before heat triggers bolting.

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.

A biennial Mediterranean herb in the carrot family (Apiaceae) grown as an annual for its leaves. The garden 'parsley worm' — caterpillar of the black swallowtail butterfly (Papilio polyxenes) — feeds exclusively on Apiaceae foliage; planting parsley is among the simplest ways to host a multi-year swallowtail population. Flat-leaf (Italian) selections have stronger flavor than curly selections.

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.
