About

Quercus chrysolepis, commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak. Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat. The species is found in Mexico and in the western United States, notably in the California Coast Ranges. It is often found near creeks and drainage swales growing in moist cool microhabitats. In the wild it grows across North America, Arizona, California, Mexico Northeast, Mexico Northwest and other regions. Grow it in full sun and most soil types. In UK gardens it is very hardy across most of the UK (RHS H6). It works well for architectural. It tolerates soil of any pH, moist but well-drained conditions and east-facing, north-facing, south-facing and west-facing aspects. Plant in well-drained soil in sun or part shade.
