Positive Rickwebb On Sep 19, 2014, Rickwebb from Downingtown, PA wrote:

This is an irregular scrubby pine tree that grows around the Great Lakes Region and in much of Canada. I've seen it the most in central Minnesota around Brainerd. It is fast growing and prefers acid, sandy soils, but I have seen a few planted in the Chicago, IL, area in barely acid, silty soils. It always has its curved pine cones present that open best after a forest fire. It is very similar to the Virginia Pine of the East Coast and South; the latter having longer needles. I really like pine trees, even the scrubby ones.

Jack pines make up a good portion of the boreal forest cover, often found with tamarack, aspen and paper birch. They establish in very dry, rocky soil that other trees can't grow in, and areas recently burned. It is the best adapted of all boreal conifers to fire.

Jack pines aren't considered attractive trees for landscaping. They have an irregular form, dead branches self-prune poorly and cones are retained for several years. They are also very intolerant of shade. Jack pines can be attacked by lodgepole pine dwarf mistletoe (Arceuthobium americanum), a parasitic plant.

This pine produces poor timber, but is useful, because it will grow in northern areas of dry, infertile soil that would otherwise support no tree growth.

The Jack Pine has very short needles, only 1" to 1 1/2" long. The 1 1/2" to 2 1/2" cones are usually curved or bulging on one side. They are thornless, or have very tiny prickles. Fires will cause the cones to open and release the seeds.

No other pine that grows so far North has such short needles or curved cones. A tree that has it's southern range in our northernmost states, it mainly grows across Canada.
