Are Shasta daisies native to Pennsylvania?

Shasta daisies (Leucanthemum × superbum) are not native to Pennsylvania; they are a hybrid species developed in the early 20th century. The plant was created from native daisies, including the oxeye daisy (Leucanthemum vulgare), which is native to parts of North America. While Shasta daisies can thrive in Pennsylvania's climate, they are considered non-native ornamental plants.
