The South Carolina Botanical Gardens' app will guide you through the gardens. At each new area you will be invited to see a listing of the plant material, along with detailed information. Beacons will pop up alerts as you travel through the garden, notifying you of things to either observe or be aware of. Access to the garden database is offered throughout, and the ability to search for specific plants and their location in the garden.
Remember, the menu is the icon in the top left. More instructions are on the info screen.
