Withania Origanifolia (_Pampas Lily-of-the-Valley_).--A hardy climbing
plant, attaining a height of 20 or 30 ft. in a very short period. The
foliage is small, but very dense and of a dark green, the flowers
being white. It may be raised from seed, and when once established the
roots may remain undisturbed for any length of time, merely removing
the stems as soon as they are destroyed by frost.
