The plant commonly known as “purple velvet weed” captivates with its distinct appearance. Its leaves, cloaked in fine, iridescent purple hairs, create a soft, velvety texture, making it a popular choice for indoor gardens.
Identifying Purple Velvet Plant
The purple velvet plant (Gynura aurantiaca, or Purple Passion Plant) is distinguished by the velvety texture and rich purple hue of its leaves, covered in tiny, vivid purple hairs. These ovate to elliptic leaves can grow up to 8 inches long and often have serrated or coarsely-toothed margins. It typically exhibits a sprawling or trailing growth habit, suitable for hanging baskets or containers. While primarily grown for its striking foliage, it can produce small, orange-yellow, daisy-like flowers, though their pungent odor makes them less attractive.
Understanding Its “Weed” Status
The common name “purple velvet weed” is misleading; Gynura aurantiaca is primarily cultivated as an ornamental houseplant, not a noxious weed. Native to Southeast Asia, it is appreciated for its unique appearance. While not invasive in most climates, its vigorous growth and ease of propagation might lead some to perceive it as “weedy” if not managed. It remains a beloved decorative plant.
Caring for Purple Velvet Plant
Light Needs
The purple velvet plant thrives in bright, indirect light to maintain its vibrant purple coloration. Too much direct sunlight can scorch leaves, while insufficient light leads to fading hues and leggy growth. An east-facing window or filtered sunlight is ideal.
Watering Practices
Consistent moisture is important, but the purple velvet plant is sensitive to overwatering, which can lead to root rot. Water when the top inch of soil feels dry. Ensure adequate drainage holes to prevent waterlogging. Reduce watering frequency during fall and winter when growth slows.
Soil and Potting
A well-draining, rich, and slightly acidic potting mix is preferred for Gynura aurantiaca. A suitable blend includes peat moss, perlite, or sand to enhance drainage and aeration. Use a pot with good drainage holes to prevent water accumulation. Repot every one to two years, or when the plant becomes root-bound, for continued healthy growth.
Temperature and Humidity
This tropical plant flourishes in warm temperatures, ideally 60°F to 75°F (15°C to 24°C). It is sensitive to cold drafts and sudden temperature fluctuations. Moderate to high humidity (60-80%) is beneficial for maintaining its velvety texture. Avoid misting leaves directly, as fine hairs can trap water and lead to rot.
Fertilizing
During the active growing season (spring and summer), fertilize every two to four weeks. Use a balanced, water-soluble fertilizer diluted to half strength. Over-fertilization can cause leaf burn and stunted growth. Reduce or cease fertilization during fall and winter when growth slows.
Pruning for Growth
Regular pruning helps maintain a bushy, compact shape and encourages new growth. Pinch back leggy stems, especially after flowering, to prevent sprawling. Remove any yellowing or damaged leaves to promote overall plant health. Pruning can be done throughout the growing season, two to three times per year.
Propagating Purple Velvet Plant
Propagating the purple velvet plant is straightforward, primarily through stem cuttings. Select a healthy stem with at least two to three leaf nodes and cut a 4-6 inch section just below a node. Remove lower leaves, leaving a few at the top.
Cuttings can be rooted in water or moist, well-draining soil. If rooting in soil, plant the cutting in a small pot and cover with a clear plastic bag to create a humid environment. Roots develop within two to three weeks, after which the new plant can be cared for as a mature specimen.
Common Issues and Troubleshooting
Several common issues can affect the purple velvet plant, but most are manageable. Fading purple coloration or leggy growth usually indicates insufficient light. Wilting leaves often signal improper watering; check soil moisture and adjust practices. While relatively resistant, purple velvet plants can occasionally attract pests like spider mites, aphids, or mealybugs, which can be managed with insecticidal soap or neem oil.
