I just wanted to give everyone a heads up about the app "like that garden" for your phone. I've been using it for a few months and it does a pretty good job of helping you identify plants. It really helps if the plant is flowering at the time of the picture. Just snap a picture and it gives you the possible results. I recommend it, its helped me a bunch

Thanks! On your recommendation I've downloaded it, but I can't find out how to upload previously taken photos, so I'll have to wait until I'm in front of the plants again, preferably while they are flowering.
