The most widely available types of peperomias are:
Emerald Ripple Peperomia: (Peperomia caperata)
Heart shaped leaves and foliage texture similar to a waffle make growing a pleasure. The attractive leaves and stems may have a silvery or burgundy tint peeking through the green.
Watermelon Peperomia: (Peperomia argyreia)
Have silver stripes with elliptical shaped leaves. Both this and the previous Peperomia plant reach only 8 inches (20 cm.) in height and width if planted in a container large enough to allow for root development. Plants have a mounding habit with draping leaves.
Baby Rubber Plant: (Peperomia obtusifolia)
This plant grows upright. Some of these types of Peperomias have solid green, shiny leaves, while others are variegated with gold and white coloration. Peperomia obtusifolia `Minima’ is a dwarf specimen, reaching about half the size of the standard.
Peperomia like medium to low light, away from direct sun. You may also grow Peperomia plants under fluorescent lighting. Water Peperomia houseplants sparingly and allow the soil to dry as deep as 5 inches between waterings.
