In the blog posting “How to grow Japanese black pine from seed” Jonas describes collecting pine cones, to grow JBP seedlings.
Question is, how do you go about identifying a pine tree to be JBP? What do you look for, to determine if a particular pine tree is JBP. I live in Pleasanton, CA, I see plenty of irregularly growing (not upright) pine trees, but can’t really tell if they are JBP. Can you please describe what characteristics (visual/sensory) to look for?
