Chinese Money Plants (Pilea peperomioides) and Peperomia plants are popular houseplants. Their similar appeal and relatively easy care can lead to confusion. This article clarifies the distinctions between these plants and provides specific guidance on their care.
Distinguishing Features
The Chinese Money Plant features unique, coin-shaped, glossy dark green leaves. These circular leaves, up to 4 inches in diameter, are peltate, meaning their long stems attach near the center, giving them a lily pad or “floating” appearance. The plant grows upright, typically reaching about 12 inches in height and width, with a distinct central stem that can become woody at the base as it matures.
In contrast, Peperomia is a large genus within the Piperaceae family, encompassing over 1,000 diverse species. Peperomia species exhibit a wide array of leaf shapes, textures, and colors, including heart-shaped, rounded, or elongated leaves that can be smooth, glossy, textured, or fuzzy. Their growth habits also vary significantly, ranging from upright and bushy to trailing or cascading forms. Many Peperomia varieties have thick, fleshy leaves that store water, contributing to their succulent-like qualities.
Comparative Care Requirements
Light
Chinese Money Plants thrive in bright, indirect light. Placing them near an east or west-facing window is ideal, as direct sun exposure can scorch their leaves. Insufficient light can lead to leggy growth and smaller, duller leaves.
Peperomia plants generally prefer bright, indirect light. Some species can tolerate lower light levels, though this might result in slower growth. Direct sunlight should be avoided for most Peperomia varieties, as it can cause leaf burn.
Water
Chinese Money Plants prefer their soil to dry out between waterings, typically when the top 1-2 inches of soil feel dry to the touch. Overwatering can lead to root rot and yellowing leaves. The plant will often show signs of thirst, such as slightly drooping leaves, indicating it needs water.
Peperomia plants require less frequent watering than Chinese Money Plants. Allow 50% to 75% of the soil volume to dry out before watering, as they are highly susceptible to root rot if overwatered.
Soil and Potting
A well-draining potting mix is important for Chinese Money Plants. Amending the soil with perlite or coarse sand improves drainage. Using a pot with drainage holes is also essential.
Peperomia plants require a well-draining, airy potting mix. A mix designed for succulents or a blend of potting soil with perlite or coarse sand works well. Good drainage prevents root rot in Peperomia.
Temperature and Humidity
Chinese Money Plants thrive in average room temperatures, between 65-75°F (18-24°C). While they tolerate average household humidity, they appreciate higher levels. Protect them from cold drafts and extreme temperature fluctuations.
Peperomia plants prefer similar average room temperatures, ranging from 65-80°F (18-27°C). Most varieties tolerate average household humidity, but many benefit from increased humidity, especially in dry environments.
Fertilization
Chinese Money Plants benefit from light fertilization during their active growing season in spring and summer. A balanced liquid houseplant fertilizer, diluted to half strength, applied monthly, is sufficient. Fertilizing is not needed during the dormant fall and winter months.
Peperomia plants are not heavy feeders and require sparse fertilization. During the spring and summer growing season, a balanced, water-soluble fertilizer diluted to half strength can be applied every 4-6 weeks or monthly.
Propagation Methods
Chinese Money Plants are readily propagated from “pups” or offsets that emerge from the main stem or soil around the mother plant. These offshoots can be carefully separated with roots and planted into moist soil or rooted in water. Stem cuttings can also be used, though separating pups is often the easiest and most reliable method.
Peperomia plants are versatile in their propagation. They can be propagated through stem cuttings, leaf cuttings, or division, depending on the species. Stem cuttings root in water or directly in soil. For leaf cuttings, a healthy leaf with a small portion of its stem can be placed in moist soil or water to encourage root development.
Common Issues and Solutions
Chinese Money Plants can exhibit yellowing leaves, often a sign of overwatering or, less commonly, underwatering. Drooping leaves indicate a need for water, while leggy growth suggests insufficient light. Common houseplant pests like spider mites and mealybugs can also affect them. Proper watering and adequate light help prevent most issues.
Peperomia plants are susceptible to root rot from overwatering, which can manifest as mushy stems or wilting. Wilting can also indicate underwatering, and crispy leaves might suggest low humidity or thirst. They can also encounter common houseplant pests. Adjusting watering practices and ensuring good air circulation are important preventative measures.
Choosing the Right Plant for Your Home
Both Chinese Money Plants and Peperomia varieties are popular houseplants due to their attractive foliage and manageable care. The Chinese Money Plant offers a distinctive, sculptural look with its round, floating leaves and upright growth habit. Its ease of producing “pups” makes it a rewarding plant for sharing.
Peperomia provides variety in leaf shape, texture, and growth form, allowing for diverse aesthetic choices. Many Peperomia species have a more compact growth habit and are known for their drought tolerance due to their succulent-like leaves. Considering your available light, watering habits, and preference for unique aesthetics versus a wide range of forms can help select the plant that best suits your home.
