Peperomia (radiator plant) is one of the 2 large genera of the Piperaceae family, with more than 1000 recorded species. Most of them are compact, small perennial epiphytes growing on rotten wood. More than 1500 species have been recorded, occurring in all tropical and subtropical regions of the world, though concentrated to Central America and northern South America. A limited number of species (around 17) are found in Africa. Though varying considerably in appearance (see gallery below), these species generally have thick, stout stems and fleshy leaves, sometimes with leaf windows. Peperomia flowers typically come in yellow to brown conical spikes. These tropical perennials are grown for their ornamental foliage.They are mostly natives of tropical America. They are compact and usually do not exceed 12 inches (30 cm) in height. They vary considerably in appearance. Some have threadlike, trailing stems and some have fleshy, stout stems.
