Clear another acre for this one. No flimsy wooden trellis for this plant. Keep it away from anything that isn't well-attached and small children. In the catalogues, another thing to watch out for is the care descriptions. The amount of care is directly proportionate to the number of adjectives used.
Nothing is really maintenance-free but it can be close to it once established.
After the first year there should be little or no weeding necessary. When a plant is recommended for naturalizing it is probably a weed, but I mean that in a nice way. It will grow with little attention and spread quickly, usually in a spot where nothing else will grow. Be prepared to ignore it.
