There are somewhere around 40 species of snapdragons, many of which have become naturalized in regions of North American. Antirrhinum majus is the common variety that makes a great addition to the cottage garden. Snapdragons do best in cooler climates, so I have mine growing in a semi-shady area where they are slower to bloom and longer lived.
I was lazy and didn't pull my snapdragons, so I was surprised to find them still growing through the winter, keeping their foliage even in single-digit temps at night. Now they're bushy and green this spring.
