Ivy-leaved morning glory is also called Ipomea hederacea var integriuscula when the leaves are entire rather than three lobed. A very common weed of New Jersey and somewhat difficult to control because the seeds are able to germinate from depths of eight inches. The entire leaf variety is often mistaken for a bindweed and vice-versa.
