Description
Considered one of the only 2-needle pines with blue/green foliage this would be a great identification feature if there wasn’t so much variation. Color varies from olive green, gray/green to blue/green. This image shows the most common form: 2-needles per bundle, blue/green color and the characteristic twist to each needle.
