How often have I heard “it’s not invasive in my garden” or “I haven’t seen it escape into my neighborhood.” Do we see the seeds of an invasive plant blow in the wind? Where do they go?
Those seeds will settle in a location far from our eyes and away from our homes. Where has the wind taken those seeds? Where have the seeds drifted through rain gutters to stop in some swampy wet area just perfect for germination, where over time these seeds turn into healthy plants? Their roots begin to spread to the point that they become aggressive, taking over native plants that are naturally controlled by our native predators.
