What Makes This Oak Special?
Unlike its tree-form relatives that can tower overhead, this shrubby variety of Oregon white oak typically stays under 13-16 feet tall, making it perfect for smaller landscapes. As a perennial shrub, it develops multiple stems from the ground, creating an attractive, bushy form that adds structure and year-round interest to your garden.

Where Does It Call Home?
This charming oak is native to the lower 48 states, specifically thriving in California and Oregon. You’ll find it naturally growing in mountainous regions where it has adapted to challenging conditions that many garden plants simply can’t handle.
Why Consider This Oak for Your Garden?
There are plenty of reasons to fall in love with this native shrub:

Consider using it as a foundation plant, in mixed native shrub borders, or as a naturalistic hedge.

The shrub works particularly well in wildlife gardens, where its acorns feed birds and mammals, while its branches provide nesting sites. For those designing sustainable landscapes, this oak checks all the boxes for environmental responsibility.
