The Mediterranean evergreen whose leathery, glossy dark-green leaves are the bay leaf of the kitchen. Missouri Botanical Garden PlantFinder describes it as a pyramidal, aromatic evergreen tree or large shrub that can reach 60 feet but is usually seen at 10-30 feet and is often pruned to 8 feet or less for garden use. Trees are dioecious: small yellowish-green spring flowers on female plants, if pollinated, give way to single-seeded purple-black berries. Winter hardy only to USDA Zone 8, so it is grown as a clipped container houseplant farther north.

A large multi-stemmed native shrub-to-small-tree of western North America, named for the dusty powder-blue drupes that ripen in late summer over a waxy bloom. Flat-topped creamy-white flower cymes up to 10 inches across rise above pinnately compound serrated foliage in early summer, drawing birds and butterflies. The cooked fruit is edible and prized for jelly, pie, and wine, but the plant earns a "high maintenance" note for suckering, wind/snow breakage, and a roster of fungal and insect pests.

A vigorous, semi-evergreen climbing vine from subtropical southern South America, grown for its intricate, unmistakable flowers — white-to-pale-blue petals beneath a crown of blue-and-purple-banded filaments. POWO (Kew) and Flora e Funga do Brasil record it as native to southern Brazil, Argentina, Uruguay and Paraguay. It is by far the hardiest commonly-grown passionflower, root-hardy to roughly zone 6b/7 and resprouting after a freeze, and it climbs fast by tendrils to clothe a fence, arch or trellis. The egg-shaped orange fruit that follows is edible but bland and insipid — it is NOT the commercial passion fruit — and the leaves and unripe fruit contain cyanogenic compounds, so only the ripe pulp is safe to eat. Its vigour is a warning as much as a virtue: in mild climates it suckers and self-seeds and can become weedy or invasive, so give it room and curb it.

The hardiest and largest of the California lilacs — a fast-growing broadleaf-evergreen shrub of the Pacific coast that smothers itself in dense thyrse clusters of pale-to-deep blue flowers in spring. Glossy three-veined, finely toothed dark-green leaves and a billowing shrub habit make it a signature blue mass on West Coast slopes. Drought tolerant once established, it asks for little summer water and resents overwatering; deer and elk browse the foliage and the bloom is a documented draw for native bees.

A small native tree with white spring flowers, edible summer berries, and copper to red fall color.

A multi-stemmed deciduous large shrub or small tree native to central China, grown for a dense early-spring display of rosy purple-pink pea-family flowers borne directly on bare branches and trunks before the leaves expand. The glossy, rounded heart-shaped leaves follow, and flat bean-like seed pods ripen and persist into winter. More shrubby and densely branched than the native eastern redbud, it makes a compact spring focal point for zones 6-9.
