DROUGHT-TOLERANT TREES SUITABLE FOR FRESNO/CLOVIS AREAAS COMPILED BY TREE FRESNO 6/02Chaste Tree (Vitex agnus-castus) is a deciduous shrub or small tree with fast growth to 25’. Habit broad and spreading, leaves are divided fanwise. Conspicuous 7” spikes of lavender-blue to pinkish-white flowers appear in the summer and fall. Tolerates many types of soils, but requires plenty of summer heat for richly colored, profuse bloom. Source: Sunset Western Garden Book, 1991 edition. Chinese Hackberry (Celtis sinesis) is a deciduous tree to 40’, nearly as wide. Branches are spreading and sometimes pendulous. Leaves to 4” long, smooth, and glossy with scallop-toothed edges. Deep root system. Especially good in windy locations, though young trees should be staked until well established. When established, trees will take wind, desert heat, much drought, and alkaline soil. Source: Sunset Western Garden Book, 1991 edition. Chinese Pistache (Pistacia chinesis) is a deciduous tree to 60’ tall by 50’ wide. Foliage colors are beautiful in fall---scarlet, crimson, orange, sometimes yellow tones. Not fussy as to soil or water; accepts moderately alkaline conditions, lawn watering (though verticillium wilt is a danger,) or no summer watering at all in deep soils. Stake young trees and prune for first few years to develop head high enough to walk under. Source: Sunset Western Garden Book, 1991 edition. Chinese Tallow (Sapium sebiferum) is a deciduous tree to 35’ high with dense or conical crown of equal width. Outstanding fall color: red, purple, yellow. Easily trained to single trunk: stake young plants securely. Branch tips may freeze back; new growth quickly covers damage, but many require thinning. Leaves are poplarlike, roundish, tapering to slender point, light green. Tiny yellowish f lowers; fruit small, clustered, grayish white, covered by a waxy coating. Give it ample water for fast growth and prune only to correct shape. Avoid planting close to sewer or irrigation lines or over sidewalk. Avoid planting near streambed or natural water source as it readily naturalizes. Source: Sunset Western Garden Book, 1991 edition.

Relatively free of pests and diseases. Outstanding spring bloom, good overhead canopy. Malus floribunda has small fruit, Malus ioensis plena rarely sets fruit. Crape Myrtle (Lagerstroemia indica) is highly valued in hot inland areas for summer flowers ranging from white to pink to purple to red. Dwarf shrubby forms and shrub-tree forms 6-30 ft. tall are available. Source: Sunset Western Garden Book, 1998 edition. Goldenrain Tree (Koelreuteria paniculata) is a deciduous tree of slow to moderate growth to 20-35’ with 10-40’ spread. Open branching, giving slight shade. Leaves to15” long with 7-15 toothed or lobed leaflets, each 1-3” long. Flower clusters in summer, 8-14” long. Fruit buff to brown in fall, hanging late.

Valuable as street, lawn, or terrace tree in difficult soils and climates. Source: Sunset Western Garden Book, 1991 edition. Gimlet, Narrow-leafed (Eucalyptus spathulata) is a small evergreen tree to 20’ with ribbonlike leaves and smooth red bark. A versatile tree, it tolerates poor soil drainage, acts as a bushy windscreen, is a good desert plant. Cream and gold flowers open in summer from long, oval buds. Bell-shaped seed capsules. Possible freeze damage in very cold winters.Source: Sunset Western Garden Book, 1991 edition.Plum, Flowering (Prunus species) will grow in almost any soil. An adaptable and choice medium-size flowering tree for lawn, patio, terrace or small street tree is P. blireiana. It also does well in planters and large tubs, but is susceptible to bacterial gall. In choosing plum to be planted in paved area, check its fruiting habits (e.g., P. cerasifera ‘Krauter Vesuvius’). When planting in a patio, prune to establish head at height to walk under. As tree develops, prune out crossing and inward-growing branches. Expect attacks from sphids, slugs, caterpillars, spider mites. Source: Sunset Western Garden Book, 1998 edition. Redbud, Western (Cercis occidentalis) grows to 10-18 feet with equal spread. Usually grows several trunks from base. All-year interest. In spring it delivers 3-week display of brilliant magenta flowers; summer foliage of handsome blue-green, leaves notched or rounded at tip; in fall, whole plant turns light yellow orred; in winter, bare branches in picturesque pattern hold reddish brown seed pods.. Excellent for dry, seldom watered banks. Water regularly in first year or two to speed growth. Thereafter, needs minimal water inland. Source: Sunset Western Garden Book, 1998 edition. Sumac, African (Rhus lancea) is an evergreen tree to 25 ft. Open, spreading habit; graceful weeping outer branchlets. Pea-size, berrylike, yellow or red fruit grows in clusters on female tree, can be messy on pavement. Stake and prune to establish form you want. Can be trained into a single-trunk tree or let it grow as multitrunked tree that looks somewhat like olive. Source: Sunset Western Garden Book, 1998 edition.

Limbs often picturesquely twisted; long, drooping outer branches sometimes sweep ground. Deeply lobed leaves, lobes rounded. Tolerates high heat and moderate alkalinity in its native range. Best in deep soils where it can tap ground water; in such situations, it can grow fast (2-3’ a year.) Magnificent tree for shading really big outdoor living area (debris makes it difficult for beds of small plants or heavily paved areas.) Source: Sunset Western Garden Book, 1991 edition. |
