Also like a creeper, but in a plant version.
A plant that infests an whole area of land, and replaces the original plant with it's own kind. Like a weed. Even if you get rid of the plant It will always come back, unless you get a gardener / plant exterminator to get rid of it.
The ivy is such a plant creeper! It's climbs up my house, and when I cut it down, it always comes back!
