If you're in the midst of landscaping your property we encourage you to GO NATIVE. The East Multnomah Soil and Water Conservation District has a Native Plant Sale each winter where they offer native plants to the public at a very low cost ($3/plant!).
These plants make a beautiful addition to any property and because they are climate appropriate they are also more likely to thrive. Place your order for plants on January 16th and pick them up one month later on February 16th.
