This full Moon heralded the appearance of the moss pink, or wild ground phlox (one of the first spring flowers). It is also known as the Sprouting Grass Moon, the Egg Moon, and the Fish Moon. Historically, Native Americans living in what is now the northern and eastern United States kept track of the seasons by giving a distinctive name to each full Moon. This name was used to refer to the entire month in which the Moon occurred. With some variations, the same Moon names were used throughout the Algonquian tribes from New England to Lake Superior.
