Hi, I just bought four tiny flats of Blue Star Creeper, thinking I would break each into mini plugs and plant them on a hill in our backyard that doesn't seem to grow grass well. Also, I was hoping we could grow something there that would sort of blend in with the grass around it, and wouldn't have to mow that part. The are is maybe 5x10' in between two trees. I was just reading something online that worried me about this really spreading and "taking over." Would you recommend this plant? Does it take over the surrounding grass, or just grow up to the existing grass after it spreads? Could it climb over the mulch of the two nearby trees and hurt those? Please advise..I'd rather return it and look for something else if this is a bad plant.
