Reply to comment by trailerhippie in TIL Snow is an excellent insulator because it consists of about 90–95 percent trapped air (fresh). This is the reason why igloos are warmer inside than outside, and why some animals in colder regions build snow caves to spend the winter while hibernating. by SunCloud-777

Your dad was mostly right. Most all plants native to an area are native precisely because they are capable of handling the weather patterns.

In the US, there are weather zone planting guides that help determine if a tree or shrub would thrive where you live. If you want to plant something that will live as long as what your grandma planted, they are decent references.
