Plant Flashcards APP
Tap the button that has the name that matches the plant photograph. Swipe on photos to see more photos of the plant. Tap a photo to enlarge it. Select the cycle button to see a new plant. When you've selected the plant, you can see more plant details, from PlantPlaces.com, by tapping on the status bar at the bottom.
Want to study a subset of plants? You can set filter text in the Settings pane, and you'll see only plants that contain that filter text. You can also choose difficulty - easy, medium, and hard.
