Huckleberry

Quercus vaccinifolia (Fagaceae) is a prostrate to low-growing evergreen shrub native to the mountains of southwestern Oregon and California. It grows only about 1 foot tall (occasionally to 4 feet), making it the lowest-growing oak known. The small, entire leaves resemble those of huckleberry (Vaccinium), hence the species name.

Huckleberry oak inhabits rocky, exposed ridges and slopes at high elevations. Despite its diminutive size, 20 diseases are documented in its profile. It is rarely cultivated. The species is of interest to rock garden enthusiasts and native plant collectors.
