Mistaken identities are as common with plants as they are with people. Many folks who have admired the Pegasus Coffee House foliage mistakenly identify it as English Ivy. It's not. It is, in fact Virginia Creeper. Here are the differences:

Ivy
Ivy is a woody, evergreen climbing plant, of which there are several species. One of the most common species of ivy in the United States is (hedera helix), which is native to Africa, western Asia and Europe. According to the U.S. National Park Service, early European immigrants were likely the first to introduce the plant into North America, and grew it for its decorative appeal. English ivy is characterized by having dark green leaves with white veins, which are segmented into three to five lobes each. It will also produce seasonal berries, which are dark purple in color, and clusters of pale, yellowish-green flowers. English ivy is a voracious grower, and uses small root-like fibers and a sticky enzyme to attach itself to various types of surfaces, including wood and brick.

Virginia Creeper
Virginia creeper (parthenocissus quinquefolia) is a North American vine that is part of the grape family (vitaceae). It is characterized by having green, five-pronged leaves, which turn a brilliant red color in the autumn season (making them a great covering for outdoor structures). The plant also produces seasonal greenish-white flowers, but these are often hard to see behind the foliage. Like English ivy, the Virginia creeper is a voracious grower. Mature plants have been known to grow up to between 6 to 10 feet per year. Virginia creeper is also incredibly resilient.
