In the Great Smoky Mountains of eastern Tennessee and western North Carolina, the species can surpass 140 feet and at least a few reach 150 feet as confirmed by Will Blozan. However, it probably won't be much more than the Northampton tree. We are near the northern end of the growing range of the Tulip poplar. In the southern Appalachians Will Blozan and I have measured the species to over 170 feet. We've yet to measure one over 200 and reports of such trees are likely authors merely repeating one another.
None offer any real proof.
As far as southern and central New England, I believe that 125 to 130 feet is the upper height limit of the species. On Long Island, NY and farther south, the tree can reach 130 to 150 feet. However, it is hard to establish real limits because of height exaggerations in the big tree reports. Despite what tree books quote for this species, the Bigtooth aspen can grow tall in some locations, but 121 feet is remarkable. However, despite their period of fast growth, oaks tend to flatten out and 110 feet tends to be their limit in central Massachusetts.
