vTree is an educational and reference app developed by John Peterson. Available on the iPhone platform, this app brings the award-winning Virginia Tech digital dendrology material to your fingertips. With fact sheets for 969 woody plants from all over North America, vTree provides an in-depth description, range map, and thousands of color images of leaves, flowers, fruit, twigs, bark, and form.

One of the standout features of vTree is its ability to narrow down the species list based on your location. Using the phone's GPS or any entered address or zip code, users can easily find the woody plants specific to their area. Additionally, users can further refine the species list by answering simple tree attribute questions or by typing in a keyword. This makes it incredibly easy to identify and learn about the trees around you.

Another useful feature of vTree is the ability to send tree-related questions to "Dr. Dendro," a tree expert at Virginia Tech. Users can describe their plant or send pictures for identification assistance. This feature adds an interactive element to the app, allowing users to engage with experts and deepen their understanding of tree identification.

With over 6,400 color photographs and an extensive database, vTree is a comprehensive resource for anyone interested in tree identification. Whether you're a student, nature enthusiast, or simply curious about the trees in your surroundings, vTree is a valuable tool that provides accurate and detailed information at your fingertips.
