Pyramidal in youth, devleoping with age a large, open, wide-spreading outline with massive branches.

Hardiness

Culture

Easily transplanted; prefers deep, rich, moist, well-drained soils but will grow in about anything; full sun or very light shade; prune in winter; withstands pollution.

Landscape Use

Acceptable for open areas in parks, golf courses, campuses; use as a street tree should be restricted because it grows too large; the influx of disease problems should be closely monitored; tree shows good uniformity for being seed-grown but some segregation occurs and types resembling either parent result.

Foliage

Alternate, simple, 6 to 7 inches long, 5(8) to 10 inches wide, 3- to 5-lobed, with triangular-ovate or broad triangular, not or sparingly toothed lobes, glabrous or nearly so at maturity, medium to dark green.

Buds

Similar to P. occidentalis.

Bark

Bark is white, gray, and flaking. Can be ornamental, but also messy.

Flower

Monoecious, April, not showy, male and female similar in dense globose structures but on separate peduncles; develop with leaves.

Fruit

Syncarp (multiple fruit) of elongated, obovoid achenes, 1 inch diameter, ripening in October and persisting late into winter, usually borne 2 together although 3's and singles occur.

Propagation

Seed requires a cold treatment for 45 to 60 days. Softwood and hardwood cuttings can be rooted.

Pests
Cankerstain, anthracnose, Botryosphaeriacanker, powdery mildew, Ameircan plum border, and Sycamore lace bug.
Cultivars

'Bloodgood' - Greater resistance to anthracnose than the species, tolerates soil compaction, heat, drought, as well as severe pruning and is rapid-growing.

'Mirkovec' - Shrubby form; broad, finely lobed leaves are a mixture of pink, cream and bronze.

Ovation TM ('Morton Euclid') - Pyramid in youth, oval and spreading with age, good resistance to leaf anthracnose.
