Summarize this article:

While you are exploring the great outdoors, bring a small trail book with you to help easily identify flowers as you find them. This is a fun, exciting way to spend time in nature. Wildflower books are often sorted by region, color, and leaf type. They usually include colored photos or illustrations to help you pick out the flowers you find. You can also snap a photo of the flower and use a book when you get home. In addition to book reference guides, you can also easily use Internet references. Search for “wildflower identification sites” and browse your options. Some sites allow you to click the color, petal number, and location to help narrow down your choices. This is a great idea if you have used a reference book and are still unsure of the flower you found. Search on your app store to find an app to use. There are both free and paid versions available for most smartphone devices. Ensure the app you select covers the area where you live, as some of the apps have regional plant databases. Then, snap a photo, upload it to the app, and instantly find out the flower type.  While this is a growing option, most apps do not have information on every type of wildflower. Make sure your lens is clean when taking the photo. It is helpful to get the entire flower in the shot. If you don’t have any reference guides on you while in the woods, use your smartphone to take a reference photo. Try to capture petals, stem, and leaves of the plant in your photo. Then, visit a search engine, and drag and drop your image into the search bar and select "Search for this image." If the photo is recognized, the type of wildflower will display in your search results.  You can do this from a computer or a smartphone device. For example, snap a picture of that pinkish purplish flower you find when hiking in Greenland. Then, upload the image to a search engine. You'll find the name of the flower as well as information and facts about the species, like that it is the national flower of Greenland.

Summary:
Use a wildflower identification book to find the species while in nature. Search online for a plant database to identify the flower from home. Use an app to identify various flowers on the go. Do a reverse-image search to instantly and easily identify the flower.
