There is an plant app I use thar will identify plants. Just take a picture of it. It tells you what it thinks the plant is and some other similar options. You get to select the winner by "adding to your garden" button. it tracks the plants in your garden.

One of the pieces of information the app gives you is what is the plant considered every where in the world. The types of categories I've seen on it are native, cultivated, exotic, invasive, and potentially invasive. The app is called Picture This. I do not want to endorse it, cause it is annoying to use sometimes. But I cannot lie that it has been extremely useful. I am very close to paying for it, since as a fellow programmer I understand the people making this need to make a living.

PSA: plant identification is built into the native iOS photo viewer. If it detects something the little circled “i” button will have magic sparkles added and you can see what it thinks is pictured.
