I planted mine in a random outdoor area in a state park. Here are some pics about 1 week old. The key for me is to do it in a sort random pattern (not all lined up) and notice that I kept the surrounding groundcover. IMO leving the other groundcover helps it to blend in. And unless you are looking for it you would not notice it since there are a lot of suspicious looking plants here. I don't know what they are but they look like weed from a distance. Maybe I'll snap a shot of one and post it.

Anyway, here are pics of my outdoor plants growing like crazy in the Memphis heat. Enjoy.
