American aspen is a fast-growing native tree prized for its striking golden fall foliage and distinctive quaking leaves. It thrives in full sun to partial shade and prefers consistently moist, well-drained soils; it does not tolerate prolonged drought or waterlogging. Note that aspens spread by root suckers and can form large clonal colonies, so allow ample space in the landscape.
