Morus rubra explained

Morus rubra, commonly known as the red mulberry, is a species of mulberry native to eastern and central North America. It is found from Ontario, Minnesota, and Vermont south to southern Florida, and west as far as southeastern South Dakota, Nebraska, Kansas, and central Texas. There have been reports of isolated populations (very likely naturalized) in New Mexico, Idaho, and British Columbia.

Common in the United States, it is listed as an endangered species in Canada,^[1] and is susceptible to hybridization with the invasive white mulberry (M. alba), introduced from Asia.^[2]
