My tulip tree was planted in 1992, from a friend in IL. Provenance unknown, but obviously important. It grows in typical suburban modified strata: compact clay subsoil with a several inches of topsoil spread over the surface.

Interestingly, at -35F, about half of its buds died, but evenly scattered throughout and not at twig ends. There was no twig dieback, and surviving buds grew normally. No other winter damage ever, except a frost crack in its trunk in younger years. It bloomed for the first time this past spring, eight or so flowers, and curiously, only on the NW side of the tree.

This is a pic from last year.
