Characteristics:

Creeping Oregon grape is a much smaller, more compact member of a family valued by landscapers for their bright yellow flowers, evergreen leaves, and bluish berries. It is similar to shining Oregon grape, but is lower and more spreading, with trailing stems (repens means crawling or trailing). It is stoloniferous with stems reaching from 7.5-15 cm in height. The compound pinnate leaves have 5-7 oval leaves, generally less than twice as long as broad. The leaflet margins are edged with 15-43 spinulose teeth, and the upper surface may be glossy or dull.

The compact racemes of bright yellow flowers are found at the apex of the stems.


Habitat:

Creeping Oregon grape is a plant of open grassy to forested areas, often on north-facing slopes in the Columbia River Gorge.


Range:

Creeping Oregon grape may be found east of the Cascade Mts from eastern Washington south through Deschutes and Wasco Counties, Oregon to northeastern California, southern Nevada, New Mexico, and north to South Dakota and Alberta.

In the Columbia River Gorge, it may be found east of The Dalles between the elevations of 200'-400'.
