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 Boston Ivy. 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.

Boston Ivy
Boston Ivy is a deciduous woody vine growing to 30 m tall or more given suitable support, attaching itself by means of numerous small branched tendrils tipped with sticky disks. The leaves are simple, palmately lobed with three lobes, occasionally unlobed or with five lobes, or sufficiently deeply lobed to be palmately compound with (usually) three leaflets; the leaves range from 5–22 cm across. The flowers are inconspicuous, greenish, in clusters; the fruit is a small dark blue grape 5–10 mm diameter.
