Epicuticular wax is a coating of wax that forms a white or blueish silver film on the leaves of succulents. Once removed, it does not restore.
It is found on the stems, leaves and fruit of all different types of plants but it’s most prevalent on succulents like Echeveria, Pachyphytum, Sedeveria, Kalanchoe, and Graptoveria, to name a few.
