Papery, inflated seed sacs in hop-like clusters shed from late summer into fall, blow across lawns and drives, and pile against foundations; catkins add a brief spring mess. Leaf litter is small and light and the tree drops very little deadwood, so annual cleanup is minor.
25-40 ft tall by 15-40 ft wide with slow growth (Morton), while the largest recorded is 73 ft and 36 in dbh, so yard trees never approach that. Silvics notes losses run heaviest in trees 95 to 140 years old — a realistic ceiling set by decay rather than age — and removal falls in the small-to-mid bracket, though the wood is dense enough that haul and chip time runs longer than the trunk diameter suggests.
