Manfreda virginica is highly fragrant, especially in the evenings. I was just in the Ouachita's (of Arkansas) and saw about 300-400 stems in flower along a roadside in a very small area about 100 sq feet. These plants were about 4 feet in height. In east TX I saw some scattered plants in a powerline ROW that were nearly 8 feet and strictly upright. In the garden, my Tennessee forms are usually about 6 feet and arching.
The species varies a lot. The leaf maculation and habit is something to watch for. Most forms have faint red at their leaf bases, but some are glaucous-green - these usually flaccid. I have some from the Ozarks that are relatively stiff leaved, undulate margined and nearly completely red spotted base to apex.

Dennis,
But the flowers on ours are definitely fragrant, as were all of the ones
in the population from which this one came (now covered with concrete).
