Tap root trees in oregon

Asked August 27, 2014, 7:38 PM EDT

what if any native to the northwest trees have a tap root? I'm looking for a tree that can be planted between the curb and sidewalk that will not push the sidewalk up. the distance between is approximately 4 feet. What tree would be recommended?

Although there are many benefits to using native plants in urban landscapes, most of our native trees (whether they have a central taproot or not) are not ideal for planting strips because they get so large. The City of Portland has a good list of street trees for different planting strip widths:

So does the City of Lake Oswego:

It looks like cascara is the only native on either of these lists for a 4 ft planting strip.

Consider using native shrubs in other parts of your landscape to benefit local wildlife, pollinators, and reduce watering needs.
