A native ground cover with a moderate growth rate to 18" high and 6' to 9' wide. Gray-green hairy leaves. Small rose to purple flowers in a flower head to 3/4" wide. Attracts butterflies. Food plant for the Southern Dogface and Reakirt's Blue caterpillars. Roots as it spreads. Erosion control on slopes. Does not tolerate foot traffic. Water monthly in dry season for best appearance.

Duchesnea indica: Mock Strawberry
Low to the ground with trailing stolons that root firmly in the soil. Bright green strawberry-like leaves. Yellow 1/2" flowers followed by red tasteless fruit that stands above leaves. Drought tolerant once established. Best used as a ground cover under trees or shrubs. Suitable for erosion control on moist, shaded slopes. Invasive in wet areas. Part shade in summer. Perennial. USDA hardiness zones 5-10.

Hypericum calycinum: St. Johns Wort
Rapidly spreads by vigorous underground stems. Grows to 1' high. Leaves are medium green in sun, yellow green in shade. Dies back in hard freeze then returns in spring. Yellow flowers throughout summer. Controls erosion on hillsides. Set plants 1.5' apart. Mow every 3 years in dormant season. Low to moderate water. Needs part shade in summer heat. Semi-evergreen. USDA hardiness zones 4-9.

Mahonia repens (berberis repens): Creeping Oregon Grape
Slowly grows to 1' high and 3' wide. Spreads by underground runners. Holly-like green leaves turn bronze in cold weather. Excellent ground cover and erosion fighter. Fragrant yellow flowers in dense clusters appear April to June. Edible blue berries. Drought tolerant. Needs well-drained soil. Full sun to part shade. Evergreen. USDA hardiness zones 5-9.

Myoporum parvifolium: Myoporum
Grows 3" to 6" high and 9' wide. Dense covering of light green leaves. Tiny white flowers bloom in summer followed by purple fruit. Plant 6' to 8' apart and plants will fill in within six months.

Larger Plants for Erosion Control

Acacia angustissima: Fern Acacia

Atriplex canescens: Four-Wing Saltbush

Epilobium canum: Hummingbird Trumpet

Fallugia paradoxa: Apache Plume

Lupinus succulentus: Arroyo Lupine

Nandina domestica 'Harbor Dwarf': Heavenly Bamboo

Opuntia engelmannii: Prickly Pear Cactus
A native cactus that grows to 8' tall and as wide. Wide shallow roots and large area of vertical pads allow this plant to provide good erosion control on slopes and banks. If soil elsewhere is too hard for digging, gardeners know that soil around prickly pear is soft and can easily be planted. This cactus should be removed by pickaxe and not by motorized scoop which will also remove surrounding soil. Replace cactus with any non-prickly plant that will provide erosion control. USDA hardiness zones 8-12.

Robinia neomexicana: Desert Locust


Macfadyena unguis-cati: Cat's Claw Vine
