Peperomia griseoargentea (Radiator Plant)

This slow-growing perennial is native to Central America and grows as a groundcover or low-growing, 2-foot shrub, in USDA Zones 9-11. The small ornamental plant is slow-growing and needs semi-shade and regular water to thrive.

Peperomia griseoargentea, commonly known as Radiator Plant, is an unusual and attractive evergreen perennial commonly grown indoors. It has heart-shaped, silvery-gray foliage with copper veins. The fast-growing foliage grows in rosettes and sprouts a lush, two-foot-tall plant when well maintained.

The plant is hardy enough to be grown outdoors in Zones 9-11, but it should be kept in partial shade and moderately watered. The more light it gets, the greater the chances of it growing successfully. To properly care for the Radiator Plant outdoors, water regularly until the soil is moist but not waterlogged; it is susceptible to root rot if overwatered. A mulch cover is recommended during the winter months to protect it from the cold. It can also be grown in a pot in cold regions or during the winter months, but make sure not to overwater it.

Although Peperomia griseoargentea is a slow-growing perennial, it makes up for it with its ornamental foliage and bright, cheerful colors. The Radiator Plant looks best in hanging baskets or as a lovely houseplant where its leaves can cascade down.
