There are many cultivars of this species. To my eye, most are much the same. This one claims the branches tilt downward towards their tip...Read Mores. The rest of my comments are general comments about the species:
This adaptable and pollution-tolerant species is commonly planted as a shade tree.
The June flowers are not showy but perfume the air for about two weeks, and are very attractive to honeybees and other pollinators. The French traditionally use them dried as an herbal tea. The pollen is moderately allergenic.
This tree is easy to shape and takes well to shearing and pollarding. For centuries, it has been popular in Europe for estates, parks, and allees, and also commonly used there as a hedge.
In Europe, mature trees can reach 80-90'. I rarely see it reach half that here in Massachusetts.
In Boston, this tree is commonly afflicted with aphids or scale, which excrete a rain of sticky honeydew on everything below, including benches and windshields. The fallen honeydew usually turns black with sooty mold. Systemic insecticides can be used to control the insects but also take a toll on honeybees and other pollinators.
This species also commonly produces tremendous numbers of suckers from the base of the trunk, requiring frequent maintenance and eventually producing large disfiguring burls.
This is one of the most commonly planted street trees in the northeast. I see many here that are stunted and half-dead. Perhaps it's the stingy tree pits they're given.
According to Dirr, this species suffers in the hot summers of southeastern US. It does better there with protection from afternoon sun. It rarely prospers south of Z7.
