I don't think anyone one would dispute Kudzu's almost unparalleled ability to spread, get out of control and take over in the right environments - the right environment being hot and humid but not too wet. Kudzu is extremely sensitive to frost and wet feet. I have been working on breeding a less vigorous variety. It is also almost impossible to spread by seeds - it spreads by vining and root crowns. Out of hundreds of seed trials, I've only had two sprout, and both died within days being so sensitive to conditions. Cope certainly never advocated allowing it to spread unchecked - he was quite explicit about this in his book. I would tell anyone who would not be willing to take the necessary steps in preventing its spread to simply not even consider growing it. It can be controlled with heavy grazing (especially by goats), but I would recommend only planting it in containers and trellising it - pruning/harvesting regularly to prevent it spreading unintentionally by long cines touching the ground. The way it was used, indiscriminately, for erosion control was irresponsible - but, I can almost guarantee that had vining wisteria been used in similar fashion, wisteria would be considered a contemptable "noxious" weed and not a valuable ornamental. I have, at least, a yearly battle on a small property owned by may aunt, with a wisteria vine.... the thick, tough, rope-like vines run hundreds of yards, under leaves and mulch, rooting as they go and climbing everything. Compared to the native Virginia Creeper and the "invasive" kudzu, the "ornamental" wisteria is an inedible, allergy inducing, tree and shrub, choking monster! Nor is kudzu a match for the ornamental English Ivy that has killed several large pine trees on the property. Being unwilling to use Round Up, I fight those vines essentially tooth and nail, with weed blades and a machete! Oh, and poison oak seems particularly fond of growing in and among ivy and wisteria.... that combination is my green monster.
