PLATANUS

All these trees are large, with heavy trunk (or trunks) and sculptural branch pattern. Older bark sheds in patches to reveal pale, smooth new bark beneath. Big, rough-surfaced leaves (to 10 in. across) have three to five lobes, resemble maple (Acer) leaves. Fall foliage color is yellowish to brown, not striking. Ball-shaped brown seed clusters, usually on threadlike stalks, hang on the bare branches through winter; these are prized for winter arrangements. Best in rich, deep, moist, well-drained soil. All are subject to anthracnose, which causes early leaf drop and twig dieback. Rake up and dispose of dead leaves, since fungus spores can overwinter on them. Chlorosis may be a problem in the desert.

Platanus x acerifolia

Hybrid between Platanus occidentalis and Platanus orientalis; often sold under the latter name. Grows fast to 40 to 80 ft. tall, with 30- to 40-ft. spread. Creamy new bark weathers to gray. Looks very handsome in winter. Tolerates many soil types and stands up beautifully to smog, soot, dust, and reflected heat. Susceptible to mildew. Good tree for avenue, street, park, large lawn. When pollarded to create a low, dense canopy, it can fit smaller spaces.
