Peperomia columella Rauh & Hutchison
Peperomia columella is a succulent with fleshy ascending stems densely covered with alternately arranged leaves. The stems branch profusely and send up new growth from the base. They are up to 8 inches (20 cm) tall and 0.4 inches (1 cm) in diameter. Leaves are thick and fleshy, bright green, truncated, and shaped like a horseshoe. The leaf apex is transformed into a "window" composed of water-storing tissue that allows light penetration to the interior photosynthetic tissue. Occasionally, the plant produces tail-like flowers in spring.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Peperomias are not particularly hard plants to grow, and their small size and delicate leaves make them perfect for desktops and dish gardens. They will rarely overtake their neighbors or shade them out. In short, they are perfectly mannered and attractive little plants. The biggest problems are usually related to watering. They like steadily moist soil but can be very sensitive to overwatering. Overwatered Peperomias tend to wilt or have raised, scab-like protrusions on their leaves. Do not be alarmed if your plant loses a few bottom leaves, but a massive leaf drop is usually due to a temperature change or fertilizer problem. Lastly, Peperomias are susceptible to mealybugs, so keep an eye out for cottony white masses on leaves' stems or undersides. These plants thrive when slightly pot-bound, so do not overpot them.
Repot plants in spring, especially to refresh the existing soil, but place either back into the same size container after root-pruning or go up only one pot size. The largest Peperomias remain relatively small, so they will never grow into large specimen plants. Most species can be relatively easily propagated from leaf cuttings.
