Agawam (or Rogers' Hybrid No. 15) is a hybrid grape variety. It is a crossing of Carter (another hybrid grape with Vitis labrusca and Vitis vinifera in its pedigree) and Muscat Hamburg (a Vitis vinifera cultivar). Agawam is one of the so-called Rogers' Hybrids created by E.S. Rogers in the early-to-mid-19th century, and is unique among the named cultivars of that group in that it is self-fertile. from Dewey's Pocket Series ' The nurseryman's pocket specimen book : colored from nature : fruits, flowers, ornamental trees, shrubs, roses, &c by Dewey, D.
