Peperomia Puteolata, aka Parallel Peperomia, is another stunning member of the Piperaceae family that can be added to your collection. With stiff, burgundy stems and ridged, cardboard-like leaves that have prominent veins of dark green and pale green, this Peperomia will eventually trail slightly, creating a beautiful display. Like the others, the Parallel Peperomia is non-toxic, making it safe to keep around your furry friends.
