I don't think it's Tilia henryana. Typically the "spines" of the soft spine like teeth are much longer on T. henryana than the leaves in the photo. You can find T. americana(Basswood, American Linden) with leaves with small soft "spine" like teeth like the leaves in the photo. The leaves look too large for T. henryana, which top out at about 4"x4"(10cm x 10cm), to me also. They look much closer in size to T. americana, which range from 4"x4" on the small side up to 8"x8"(20cm x 20cm), to me. Also, T. henryana in cultivation has so far been a relatively small tree in the 30' to 35' range(roughly 10m). Lastly, I'm doubtful that T. henryana(considered zone 7 hardy usually) is hardy in the zone 5 Brookfield Zoo which has seen temps as low as -20°F(-29°C) within the past 12 years or so(surely within the lifetime of this tree). So, I believe this is a Basswood tree(T. americana).

this looks like a Camellia, probably a Japonica. I could not turn the picture so it was not sideways so it was hard to look at.

Sorry, I have no idea, but the round leaves should help in identifying it. I also would suggest posting this question on the general rose forum. It is a really drop-dead gorgeous rose.

It's really the only possibility.
