[MAIPC] Houttuynia cordata management

[Mary Travaglini]

Hi all,
Anyone have successful experience managing the super nasty (and smelly) Houttuynia cordata (chameleon plant/fish stink plant)? Limited resources online for treatment, but from what I can find, it's really only responsive to triclopyr and metsulfuron methyl, with manual disturbance only making it worse. Which is the experience a friend of mine has in the DC area--in fact now that she has been pulling and digging to treat it, the darn thing is popping up 4 feet away in her and her neighbors' lawns. Does anyone else have it spreading into lawns, by the way? 
p.s. if anyone sees this at nurseries, they really need to be asked with great gusto to pull this off the shelf and make their money elsewhere--there is no non-native ground cover that can even match the nastiness of this. It has rhizomes that are 18"+ deep, and will bust up geotextiles from below, grows in sun, shade, and any soil type, so there's no containment strategies for it. Grows from tiny fragments above or below the surface, too, so becomes really dangerous if it gets mowed or pulled.
