SummerMac is another name for a seedling discovered by the Arends family in the famous apple region called Fruit Ridge, north of Grand Rapids, Michigan. Grandpa was selling trees to the grower when he was first shown this apple growing on a fence row. He was really impressed with its quality at that time of the summer, and tried to get the nursery he was selling for to get the rights to the apple and patent it. To Grandpa's consternation, they didn't take the interest that they should have and a competing nursery patented it and introduced it as Paulared(R). It went on to make them a lot of money when it became one of the most widely planted new apples in Michigan in the 1960s and 1970s.
