This tray contains a mix of different succulent varieties, all very easy to care for. These are commonly available varieties and are perfect for beginners and/or those looking for a wide variety at a low price and with a high chance of success.

 At first glance, I see Pachyphytum, Adromischus, Crassula, Senecio, Kalanchoe, Sedum, Aloe, and Echeveria. The exact species and/or hybrid names aren't always easy to determine.
