Pitch Pine has been difficult to get, as most nurseries don’t offer it. The hybrid, Pitlolly Pine, has been offered more frequently. But overall, Pitch Pine has been hardier. I lose a lot of the Pitch x Loblolly Hybrid Pines, and the ones that survive, have more Pitch in their DNA, because they are cold-hardier.
Pitch Pine grows relatively fast, but the Bigtooth Aspen suckers that are popping up grow a lot faster.
