Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

Oregon grape is a broadleaf evergreen shrub native to the northern parts of North America. It has sharpely toothed leaves. Yellow flower clusters appear in spring and turn into blue fruits later in the summer.
It will grow in both part shade and full shade but performs best with regular moisture and protection from the wind. The berries are eaten by a variety of wildlife.
Oregon grape is growing in several locations at the Xeriscape Garden. It performs best in part-shade to shady locations. The leaves sometimes deydrate over the winter and turn partially brown. They eventually get covered up by the new growth, but in can be unsightly at times.
None needed, but can be pruned to achieve a certain shape, if desired.
