I agreeChooks Chick I had the misfortune of planting a sapling Sycamore tree in 1973, I liked the big leaves. I got it at Kmart, nothing on it t said : it will be huge, it will throw abundant branches to the ground for no reason, it will have a huge branch spread that will try to get in your bedroom windows/ rub shingles off the roof.
Also it is the latest to put out leaves and the last to dump them - long after our free leaf pick-up ends. Then too, it produces big balls of seed. They were fun to throw at things because they poof and spread millions of seeds everywhere. So far I haven't seen signs of them sprouting BUT, when they poof seeds my throat gets tight and I have endless coughing. I don't bother seed balls anymore.
I would never have one again unless I had many acres and would locate it far from home., it does make good shade when it actually has leaves.

I would NOT even have 1 on any acres that I owned. Just my way thinking here.
