Magnificent oak tree from the sky islands of the Southwest. The Arizona White Oak is an extremely handsome evergreen oak that is well adapted to our climate here in the Pacific Northwest, handling our coldest winters with ease and not seeming to mind the dry summers, though it does enjoy some deep waterings in mid to late summer. Great wildlife and landscape tree.

A stunning evergreen oak from Southern California with leaves that have a wonderful bluish color to them. Englemann Oak is not often planted this far north so these are a bit of an experiment, but the seed was collected by our friend Nick Lake at the highest elevation he could find them so we’re hoping for a decent bit of cold hardiness to these.

An excellent and varied evergreen oak from Arizona and into Mexico. This widely distributed species takes different forms depending on where it is growing, but all of them are quite beautiful. This batch is from high elevations in Arizona and have proven easily hardy in our Zone 8 climate. Easy to grow in well-draining soil and enjoys an occasional deep watering in dry summer climates but also withstands drought quite well.

An evergreen oak species from Southern Arizona, the Emory Oak has been prized for millennia for its tasty acorns that have no tannins and can be eaten fresh right off the tree without any leaching. While thought to be marginally cold hardy here, these seedlings are from a particularly high elevation stand northeast of Phoenix, courtesy of the ever tenacious plant explorer Sean Hogan. The acorns are truly delicious from these trees, but it is also a gorgeous ornamental and will make a fantastic evergreen street or garden tree.

The orange ball buddleja comes from Chile and Argentina and attracts all pollinators that cross its path. Buddleja globosa can reach up to 15 feet and loves sun to partial shade and a decent bit of summer water. Prefers well drained, loamy soils and is semi evergreen. We have not found it to be invasive here in the PNW, though some other species of Buddleja are.

Latin Name: Buddleja globosa
Site and Soil: 1/2 day to full sun and well-drained soil.
Hardiness: Hardy to at 0F
Bearing Age: 4-5 years after planting

Pests & Diseases: None that we’ve seen
USDA Zone: 7

Also called the Sonoran scrub oak, the Turbinella Oak is one of the best of the shrubby oak species that grow throughout the West. The evergreen foliage is an excellent powdery blue that contrasts perfectly with the purple growth tips. Its a very drought tolerant shrub to small multi-branched tree, but can also handle some big monsoons during the growing season.
