Everybody loves a beautiful garden. Gardeners love plants that are adaptable, tough, and fast-growing. It’s even better if that plant produces showy fruits that attract birds or is an annual that self seeds, so it doesn’t need to be replanted every year. Unfortunately, many of these plant traits desirable to gardeners can also increase the likelihood that a plant jumps the garden fence and invades natural areas.
Invasive plants threaten our environment and economy. They pose an enormous threat to our native plants, animals, and ecosystems, and they cost the United States approximately $35 billion per year (www.invasivespecies.gov).
Although invasive plants are almost always not native to a region, it is important to note that most non-native species are not invasive. We use the following definitions.
Native (indigenous): A species that was present in North American prior to European settlement or has arrived since through natural means of dispersal.
Non-native (exotic, alien, introduced): A species that was brought to North America by humans, either deliberately or accidentally.
Invasive: A non-native whose introduction does or is likely to cause economic or environmental harm or harm to human health (from Federal Executive Order 13112).
People have introduced invasive species both accidentally and deliberately. This app focuses on plant species that are used ornamentally and have become invasive in at least part of the Midwest. Cultivars or hybrids produced from these species may or may not be invasive. In the few published cultivar evaluation studies, some cultivars prove to be more invasive than the parent species, others less or not invasive. We lack research about cultivar invasiveness for many of these species. When we have good evidence about a problematic or relatively benign cultivar, we list those specifically.
Suggested alternatives include both native species and non-native species that currently show no signs of becoming invasive.

A great app to raise awareness of invasive plants and encourage the planting of natives. Could use more plant suggestions and should include a native choice on each. I can think of more plants that could be promoted!
Great app for looking up alternatives to invasive species for your yard. Wish everyone would grow native!
Either no plants are listed or the app wasn't working. Either way, a waste of space. The only thing that showed up was a statement about invasive plants. I thought it would have photos and id info.
