Ipomoea pandurata, G. F. W. Mey. Man-of-the-earth. Wild Potato-vine. St. 2-12 ft. long: root very long and large (10-20 pounds): lvs. 2-4 in. long, long- petioled, usually cordate and entire, occasionally angulate, fiddle-shape or hastately 3-lobed: peduncles 1-5-fld., commonly a little longer than the petioles; corolla 2-4 in. wide, broadly funnelform with pointed lobes, white with a dark purple throat. May-Sept. Dry soils, Canada to Fla., west to Ont. and Texas. A.G.12:637. R.H. 1893:574. B.M. 1603 (as Convolvulus candicans), 1939, and Gn. 27, p. 373 (both as C. panduralus). B.R. 588.—In some places this species is a very troublesome weed, which is almost impossible to exterminate because of its long tuberous roots.

It can easily be kept within bounds in the garden with a little care, and makes a very desirable plant for covering an old dead stump or back fence. The chief merit of I. pandurata as a garden plant is its hardiness; hence it is often sold as the "hardy" or "perennial moonflower." If well mulched the roots will stand 26° below zero. There is a double-fld. form. It is sometimes escaped in cult, grounds.
