Murdannia loriformis, also known as the Philippine Violet or Jewels of Opar, is an ornamental plant that enhances indoor spaces with its unique foliage. This low-maintenance species, also referred to as Asiatic Dewflower or Beijing Grass, is adaptable for various settings, including terrariums. It is considered non-toxic, making it suitable for homes with pets.
Unique Characteristics and Appearance
Murdannia loriformis is a low-growing herbaceous perennial, characterized by slender, creeping stems that contribute to its bushy or trailing growth habit. Its foliage features narrow, grass-like leaves typically measuring between 2 to 5 centimeters in length. The leaves often display a blend of green and silver, sometimes described as a metallic sheen, especially in varieties like ‘Bright Star’. This variegation forms a rosette pattern, giving the plant a structured and compact appearance.
Beyond its leaves, Murdannia loriformis produces delicate, funnel-shaped flowers. These blooms are usually pale blue, lavender, or creamy white, emerging sporadically throughout the year, with increased frequency during warmer months. The flowers develop on new spikes that emerge from the vine’s terminals.
Cultivation and Care
Light Requirements
Murdannia loriformis thrives in bright, indirect sunlight to maintain vibrant foliage coloration. Placing the plant near an east or north-facing window, where it receives filtered light, is ideal. Direct sunlight can cause scorching and discoloration of the leaves, while insufficient light may lead to stunted growth or fading variegation.
Watering Needs
Consistent moisture is important for Murdannia loriformis, but the soil should never become waterlogged. Water the plant when the top inch or top third of the soil feels dry to the touch. Overwatering can lead to root rot, so allowing the top layer to dry slightly helps prevent this. During cooler autumn and winter months, the plant’s growth slows, necessitating a reduction in watering frequency. Using lukewarm water is preferable, as cold tap water can shock the plant.
Soil Preferences
The ideal soil mix for Murdannia loriformis is well-draining and rich in organic matter. A peat-based potting mix amended with perlite or sand works effectively to ensure good drainage while retaining some moisture. A blend of approximately 60% potting mix with 30% perlite and a small amount of orchid bark is suggested for optimal aeration and drainage. Ensure the pot has adequate drainage holes to prevent water accumulation at the roots.
Temperature and Humidity
Murdannia loriformis prefers warm temperatures, ideally ranging between 15°C to 24°C (60°F to 80°F). It is sensitive to extreme temperatures, so avoiding exposure below 10-12°C or above 29°C is advisable to prevent damage. This plant appreciates moderate to high humidity levels, typically between 50-70%. To increase humidity, consider placing the plant on a pebble tray filled with water, using a humidifier, or grouping it with other plants. While misting can help, excessive misting should be avoided as it might increase the risk of powdery mildew.
Fertilization
During the active growing season (spring and summer), Murdannia loriformis benefits from regular fertilization. Apply a balanced, water-soluble fertilizer every 2 to 3 weeks. Diluting the fertilizer to half strength can prevent over-fertilization, which could harm the plant. As the plant enters its dormant period in autumn and winter, reduce or cease fertilization entirely.
Propagation Techniques
Propagating Murdannia loriformis is a straightforward process, commonly achieved through stem cuttings or division. Stem cuttings are the easiest method for creating new plants. To take a cutting, select a healthy stem with at least two to three nodes, which are the small bumps where leaves emerge. Cut the stem approximately 3 to 4 inches long, just below a node, using clean, sharp scissors or pruning shears.
Remove any lower leaves from the cutting to prevent them from rotting once submerged. The cutting can be rooted in either water or moist potting soil. For water propagation, place the cutting in a glass jar with enough water to submerge the nodes, changing the water every 2 to 3 days to maintain freshness. Roots typically develop within 2 to 3 weeks in water. If rooting directly in soil, plant the cutting in a well-draining potting mix, ensuring the lower node is fully submerged, and keep the soil consistently moist.
Division is another effective method, particularly when the parent plant has become overcrowded. Carefully remove the plant from its pot and gently loosen the soil around the root ball. Identify natural divisions or areas where the plant can be separated, ensuring each section has a healthy set of roots and shoots. These newly divided sections can then be potted individually in fresh, well-draining potting mix.
Troubleshooting Common Problems
If leaves begin to brown, the cause could stem from several factors. Browning leaf tips that feel crispy indicate underwatering, while brown patches accompanied by yellowing across the leaves might signal overwatering. Direct sunlight can lead to brown spots in the center of leaves, a sign of scorching. Low humidity can also manifest as browning leaf tips with yellow halos.
Yellowing leaves, especially on the lower parts of the plant, frequently point to overwatering, particularly when combined with insufficient light. Providing adequate light can help the plant process moisture more efficiently. Leggy growth, where stems appear stretched with sparse foliage, indicates that the plant is not receiving enough light. Moving the plant to a brighter location with indirect light can encourage more compact and robust growth.
Root rot is a concern, typically resulting from consistently soggy soil due to overwatering or poor drainage. Symptoms include mushy, brown roots and general plant decline. Ensuring the soil is well-draining and allowing the top layer to dry between waterings are preventive measures. While Murdannia loriformis is generally resistant to pests, occasional infestations of spider mites or mealybugs can occur. Regular inspection and wiping down leaves can help prevent and manage these issues.
