Pellonia houseplants are more commonly known by the name trailing watermelon begonia, but unlike the showy begonia, they have a fairly insignificant bloom. Pellonia houseplants are primarily grown for their showy foliage and trailing habit.
An evergreen with greenish-pink stems ending in oblong, wavy-edged leaves, Pellonia houseplants are native to Southeast Asia, specifically Vietnam, Malaysia and Burma. Pellonia is usually utilized in hanging baskets but also works well in terrariums. This herbaceous perennial hails from the family Urticaceae and has a low growing (3 to 6 inches) habit with spreading or creeping tendencies (1 to 2 feet), making Pellonia useful as a ground cover in appropriate climates.
