Many of Peperomia plants are perennial epiphytes growing on rotten logs and they have thick stems and fleshy leaves, some with leaf windows. The palmate pattern of leaf veins is marked out in some species as furrows in the leaves or as colored lines. Most Peperomias have tiny flowers which are packed into a characteristic greenish or brown conical spike (spadix) like an inverted catkin. As a houseplant, it typically grows on thick erect stems. Flowers are interesting but not particularly showy.
