Watermelon peperomia (peperomia argyreia) is a tropical plant originating from South American. It gets its common name from attractively green leaves that are striped and shaped like watermelon. 

These plants are low-growing, often only reaching 30cm in height, with dwarf varieties reaching about 15 cm. Although they do develop small flower spikes, these are pretty insignificant, and the main attraction are the attractive, lush leaves.
