The coral bead plant, known for its vibrant, bead-like berries and compact growth, is a popular ornamental choice for indoor gardens. Its evergreen foliage adds year-round visual appeal.
Understanding the Coral Bead Plant
The coral bead plant (Nertera granadensis) is also called pincushion plant, coral moss, or English baby tears. This low-growing plant is native to various regions surrounding the Pacific Ocean, including areas from southern Chile and western Argentina north to Guatemala, as well as New Zealand, eastern Australia, and parts of Southeast Asia.
This plant typically forms a dense mat of tiny, dark-green leaves on intertwining stems, often resembling baby’s tears (Soleirolia soleirolii). In early summer, small, inconspicuous greenish-white flowers appear, which then develop into the plant’s most striking feature: bright orange-red, bead-like berries. These glossy berries can completely cover the foliage and remain on the plant for several months, providing a splash of color that makes the coral bead plant a favored decorative item, especially during autumn.
Growing and Caring for Coral Bead Plant
The coral bead plant thrives in bright, indirect light. Direct sunlight can scorch leaves and shrivel berries. Indoors, a south or east-facing window is suitable if shielded from intense sun. Moving the plant outdoors in spring to a semi-shaded location encourages flowering and berry production, but protect it from harsh afternoon sun.
Consistent moisture is crucial, especially in spring and summer when the soil should be kept evenly moist but not waterlogged. In fall and winter, allow the soil to dry out almost completely between waterings. High humidity is preferred; place the plant on a tray of wet pebbles or mist foliage daily during blooming until berries form.
The plant prefers a well-draining, slightly acidic soil mix. A suitable blend includes two parts peat moss or coco coir with one part perlite or pumice, plus organic matter or sand for aeration and drainage. Due to its shallow root system, a pot a few inches deep with drainage holes is ideal.
These plants prefer cooler temperatures, ranging from 55 to 65°F (13-18°C) year-round. Temperatures above 65°F (18°C) during flowering can prevent berry formation. While they tolerate brief spikes up to 80°F (26°C) or drops to 40°F (4°C), avoid prolonged exposure to extreme temperatures.
Fertilize during the spring and summer growing season. Apply a water-soluble, balanced fertilizer diluted to half strength monthly until flowering. Over-fertilization negatively impacts health, so follow product instructions. Prune as needed to maintain shape and size, and remove dead or yellowing leaves to promote overall health.
Toxicity and Safety
The coral bead plant, especially its attractive berries, is toxic if ingested by humans and pets. While toxicity is generally mild, causing symptoms like gastrointestinal distress in pets, caution is important.
Because of the berries’ appeal, especially to young children, keep the plant out of reach of children and animals. Follow safe handling practices, and promptly remove any fallen berries.
Propagation and Common Issues
The coral bead plant can be propagated through seeds, stem cuttings, or division. Division is often the easiest and most successful method: gently pull apart plant clumps in spring, ensuring each new section has roots, then plant them separately. Propagation from seeds (from berries) or tip cuttings is possible but may take longer to reach maturity.
Gardeners may encounter issues like leaf drop, often due to improper watering (too much or too little) or unfavorable environmental conditions. Overwatering and poor drainage commonly cause yellowing leaves and can lead to root rot.
Pest infestations, such as spider mites, aphids, and mealybugs, can affect coral bead plants. Regularly inspect for pests and address them promptly with treatments like insecticidal soap or neem oil. Good air circulation also helps prevent pest issues and fungal problems.
