Does anyone have Chameleon? (korean houttuynia)

This past Spring i planted a few Chameleon which are perennials. The tag read that they are relatively new introduction from Asia. They did great all summer long and i would love to add more of them next year. Now that winter is nearing i am wondering if there is any special care i need to give them for the winter or to get them ready for winter? Do i need to do anything to them such as cut them back now that we have had a couple light frosts, or can i just let them go until spring? I will post a picture of what these plants looked like after being in the ground from early spring this past season until now. They are the green plant next too the impatients. I really like these for the unique shaped leaves and there colors of yellow, green, bronze and scarlett red. The also bllom white flowers in the summer. Is anyone familiar with these and can you tell me what care i need to give them for winter?

You might want to read the comments about that one in Plant Files before you take too good care of it over the winter...it can be a rather aggressive pest in many areas. I wasn't sure if it would be badly behaved in your zone, but looking at the comments there are some people from your part of the country who've had problems with it. http://davesgarden.com/guides/pf/go/2164/

ecrane, thanks for the help. I will check out what others have to say. Thanks so much.

Ecrane, i read the plant files that u directed me too..now i am thinking i should go dig this plant up and fast!! Its only been in my flower bed for one spring/summer, and right now i could probably very easily dig it up (if it has not took hold too much). Maybe i should get rid of it?? Sounds like alot of headache down the road if i leave it in my beds. Any other comments appreciated.

The only thing that kills it here is Roundup - multiple applications. If any part of the root survives, it will begin to spread. It will cover any size bed. It does look nice, but here its aggressiveness far outweighs its beauty. I suggest killing it - good luck on the digging.

I don't agree that chameleon plant deserves so much vitriol. I really like them, and have them scattered throughout.

After all the bad press about it's smell, I trained myself to think "orange peel" before handling it, and now they smell delicious! Even better than my first, neutral appraisal, before I learned I was supposed to hate it.

For heaven's sake, daisies are invasive. So is periwinkle, bugle-weed, lily-of-the-valley, and on and on. They all have their uses. You just learn to handle them accordingly.

I love having the beautiful marbled leaves in a northern perennial, and am charmed to a grin when they sprout their darling little white flowers.

So here's one vote in favor. I think they're worth the work.

Here in Seattle this plant has been too well behaved. They were planted several years ago and the only negative thing I have to say about them is that occacionally I have to pull the plain green ones that emerge. I love the colors and it is welcome to cover more ground than it has.

A trick I have learned to contol plants that can be invasive is to cut the bottom out of a plasic nursery container and put it in the ground around the plant. By doing this it can't spread by the roots, it works for mint. I may have to try this one it is pretty.
