Western redbud

Cercis occidentalis
A western North American native large shrub or small multi-stemmed tree that erupts in clouds of magenta-pink pea-family flowers along bare branches in early spring - often before the leaves expand. The round, heart-shaped blue-green leaves with palmate venation follow, and flat 2-4 inch seed pods ripen burgundy-red and persist into winter. A drought-tolerant, butterfly- and bee-supporting native of dry slopes from northern California east to southern Utah and south to Arizona.

Blue elderberry (Sambucus nigra ssp. cerulea) showing the diagnostic cluster of glaucous powder-blue drupes with their waxy bloom, hanging amid pinnately compound serrated leaves.
Sambucus nigra ssp. cerulea
Blue elderberry
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.

Blueblossom (Ceanothus thyrsiflorus) shrub covered in dense pale-blue thyrse flower clusters above glossy three-veined dark-green leaves.
Ceanothus thyrsiflorus
Blueblossom
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.

Heteromeles arbutifolia
Toyon
The signature evergreen shrub of the California chaparral and coastal foothills - leathery, sharply toothed dark-green leaves, flat-topped clusters of small white summer flowers, and the brilliant red pomes that earned it the names Christmasberry and California holly (and, by way of the Hollywood hills, supposedly the name "Hollywood"). Long-lived and deeply drought-tolerant; the winter berries feed more than twenty bird species when little else is fruiting.

American elderberry (Sambucus canadensis) mature multi-stemmed shrub in flower, showing its arching-cane habit with flat-topped white flower cymes over pinnate foliage.
Sambucus canadensis
American elderberry
A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5 to 12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh - they are cooked into jelly, pie, and wine.

Prunus americana
American plum
A small native deciduous tree (or thicket-forming, suckering shrub) of eastern and central North America, grown for clouds of fragrant white 5-petaled flowers that open in March before the leaves and for the edible red plums that follow in early summer. It forms a broad, spreading crown with attractive dark reddish-brown twigs that sometimes carry thorny lateral branchlets. A documented larval host for swallowtails and other butterflies, with flowers of special value to native, bumble, and honey bees.

Prunus serotina
Black cherry
The largest native cherry of eastern North America - a medium-to-large deciduous shade tree that hangs elongated racemes of small white flowers in spring, then ripens drooping strings of pea-sized fruit from red to near-black in late summer. The fragrant white bloom feeds bees while the fruit is eaten by 33 species of birds and many mammals; it is also a workhorse larval host, supporting the Eastern Tiger Swallowtail and a string of giant silk and sphinx moths. Every part except the ripe fruit is cyanide-bearing and toxic.
