Radiator Plant
Peperomia rotundifolia has a number of common names, including Yerba Linda and creeping peperomia, creeping buttons, royal velvet plant, and my favorite the Radiator Plant. So you can tell that this is a well travelled plant.
Here we see a fully blooming specimen creeping along a tree branch in it’s original habitat high up in the Cloud Forests of Costa Rica, although it’s range runs from Mexico to Brazil. My book also says it can be found in Tanzania, but that can’t be right.
