Velvetleaf is a rather tall and lanky plant with large leaves that is easy to identify in the field because there is really nothing else that resembles it. There are other weedy members of the Mallow family that have been introduced from abroad, but they are much smaller plants. Velvetleaf is about as tall as the native Hibiscus spp.
(Rose Mallows), but the latter are perennials with darker foliage and much larger flowers. The seeds of Velvetleaf are reportedly edible. In an outdoor emergency, the soft leaves can be used as a substitute for toilet paper.
