Flower apps and plant ID tools keep getting better. Are you an amateur botanist, a hiker confronted by an unfamiliar tree on a trail, or a gardener who snaps a photo of a mystery plant you’d like to grow? There’s an app for that. Here’s a roundup of 10 mobile apps to identify wildflowers, trees, and houseplants:

Leafsnap uses visual recognition software to identify all 185 tree species in the Northeastern US from photos of their leaves. (Coincidentally, Leafsnap was developed by my friend Peter Belhumeur, a researcher at Columbia University.) The high-resolution images were created by the conservation organization. Finding Species.

An interactive plant ID app, [email protected] allows you to take photos of plant parts (such as bark, leaf, or flower) and upload them to compare with images in the app’s botanical databases to find the closest matches. Developed by French researchers, the app’s databases contain 3,700 species found in French.

Flowerida

An app to identify Florida wildflowers, filtering them by such characteristics as number of petals and bloom color, Flowerida is 99 cents and optimized for iPhone 5.

Says developer Eric Beard, “So far I have only visited parks and preserves within a few hours of Tampa, so the images are a good sample of what’s common in Southwest Florida.  I have 92 images in the app so far, with another dozen or so that I’ve identified but haven’t added yet. And beyond that I have about a dozen that I can’t identify, despite digging through a giant stack of wildflower books.”
