Peperomia clusiifolia aka Baby Rubberplant

Peperomia clusiifolia is a small evergreen plant from Jamaica. It belongs to the pepper family, Piperaceae. Its common names include red edge peperomia and baby rubber plant. In the wild, it grows as an epiphyte in wet tropical climates. Gardeners grow it indoors for its leaves rather than flowers. It suits pots in homes, greenhouses, and conservatories.

The plant grows upright and forms a low mound. Its thick leaves give it a succulent form. Plants often reach 0.5–1 foot (0.15–0.3 m) tall and wide. RHS gives an upper size of about 1.6 feet (0.5 m) in both directions. Growth is slow, and reaching full size can take five to ten years. The simple leaves are stiff, smooth, and glossy. They range from rounded to oval, with no hairs. Deep green leaf blades have thin red or maroon edges. The edges are smooth rather than toothed. Its stems have no scent.

Small flowers grow along thin spikes in pale green and white. They may appear in spring and summer. Plants kept indoors seldom bloom. The leaves therefore provide most of the plant's year-round interest. Their dark colour and red edges make a useful accent. A pot can display the plant without relying on flowers. Its compact size also makes it suited to container growing.

Give it bright light without direct sun, or partial shade. It can also cope with low light. Use moist soil that lets excess water drain away. Loam suits it, and sandy soil is also listed. It accepts acid, neutral, and alkaline soil. Avoid cold drafts and too much water. Its USDA range is zones 10–12. RHS rates it H2, so it cannot survive freezing. Slow growth means it needs repotting less often. It needs little routine care and no regular pruning. Trim it only to keep its shape compact. Division and leaf cuttings offer ways to make new plants.

RHS reports few usual pest or disease troubles. Still, check for mealybugs, spider mites, aphids, and scale. Fungus gnats and whiteflies may also occur. Excess water can lead to root rot. Keep water off the leaves to reduce leaf spot risk. ASPCA lists this species as non-toxic to dogs, cats, and horses. That safety rating does not establish its value as food.
