Tap root trees in oregon
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.
