As for the bald cypress, apparently there's a healthy one all the way up in Jefferson, NH.

A vertical height of 21ft isn't exactly "big" though.
If anyone wants some northern catalpa come on over and get some. They need to be transplanted from one of my big fabric pots. It's cost Legro a NWS weighing gauge though.
