Title: Is Carolina laurel (Prunus caroliniana) a good choice for San Juan Islands, Washington?
Answered by: Nan Hampton
Here are some alternative possibilities for evergreen shrubs/trees that are native to San Juan County, Washington:
1. Arctostaphylos columbiana (Hairy manzanita) reaches 5-10 feet. You can see more photos of Arctostaphylos columbiana from Oregon State University.
2. Vaccinium ovata (Evergreen huckleberry) grows up to 10 feet tall.
3. Arbutus menziesii (Pacific madrone) can grow to be a large tree (up to 100 feet); but, of course, it does start smaller and takes a while to get to its full height.
4. Taxus brevifolia (Pacific yew) is another evergreen native to the San Juans that can grow to 50 feet, but is slow growing.
5. Gaultheria shallon (salal) grows to 1-4 feet.
6. Mahonia aquifolium (hollyleaved barberry) grows 3-6 feet tall.
The Green Guru hopes you can find an acceptable alternative to Carolina laurel among these.
