Platanus occidentalis
American Sycamore is a very large, deciduous tree, achieving massive height and girth. It is monoecious; male and female flowers appear on separate trees. Fertilized female flowers give way to spherical, airy balls of seeds, which disintegrate as they are weathered. Sycamore features large, lobed, dark green leaves and irregularly exfoliating (peeling) bark, revealing an attractive pattern of jigsawed colors. Sycamore is tolerant of urban conditions and highly valued as a native tree. It is susceptible to anthracnose (a fungal plant disease), which causes temporary defoliation, but the leaves grow back quickly. Plant it as a specimen in your large yard, or as a street tree in your neighborhood.
