Dirrs Tree and Shrub Finder
I think this app is really extremely good. The information is first-rate and the app is really easy to use, excellent for someone who needs to get accurate information quickly. However, I have to confess that Im a little disappointed that there arent photos for every one of the plants in the finder. A picture is worth a thousand words...especially if you dont happen to know that particular species.
