The purple passion plant, Gynura aurantiaca, offers a striking addition to indoor plant collections with its unique, velvety foliage. Its leaves are covered in fine, deep purple hairs, giving the plant a vibrant, iridescent appearance under light. This distinctive texture and coloration make it a popular choice for those seeking an eye-catching houseplant.
Purple Passion Plant Care
Providing the correct light conditions helps maintain the vibrant purple coloration of the Gynura aurantiaca. Bright, indirect light is ideal, such as that from an east or north-facing window, or a few feet away from a south or west-facing window. Insufficient light can cause the plant to lose its intense purple hue, resulting in greener or duller foliage. Conversely, direct afternoon sunlight can scorch the delicate leaves and fade their color, so protection from harsh rays is important.
A well-draining potting mix, often composed of peat, perlite, and pine bark, promotes aeration and prevents waterlogging around the roots. Good drainage is important to prevent root rot. Ensuring the pot has drainage holes further aids in preventing excess moisture accumulation.
Water the purple passion plant when the top inch (about 2.5 cm) of soil feels dry to the touch. Allow water to drain thoroughly from the bottom of the pot, discarding any excess water that collects in the saucer. Overwatering is a common issue that can lead to root rot, so consistency in checking soil moisture is beneficial.
These plants prefer average room temperatures, typically ranging from 65°F to 75°F (18°C to 24°C). Avoid exposing them to sudden temperature fluctuations or drafts from windows and air conditioning vents. While average household humidity is often sufficient, providing higher humidity, such as through a pebble tray or a humidifier, can benefit the plant, especially in drier indoor environments.
During spring and summer, feed the purple passion plant every two to four weeks with a balanced liquid houseplant fertilizer, diluted to half strength. Suspend fertilization during the fall and winter months when the plant’s growth naturally slows. Over-fertilization can lead to nutrient burn and damage the roots, so adherence to recommended dilutions is important.
Repotting Your Purple Passion Plant
Repotting becomes necessary when the purple passion plant outgrows its current container, typically every one to two years. Signs include roots circling the inside of the pot or emerging from the drainage holes. Another indication is if the soil dries out much faster than usual, suggesting a dense root ball. Moving the plant to a slightly larger pot provides room for continued root and foliage development.
When repotting, select a new pot that is only one or two inches larger in diameter. Using a fresh, well-draining potting mix helps replenish nutrients and provides a healthy new environment for the roots. Carefully remove the plant, gently loosen any compacted roots, and center it in the new container. Fill around the root ball with fresh soil, ensuring the plant is at the same depth as it was previously, then water thoroughly.
Propagating Purple Passion Plants
Propagating purple passion plants through stem cuttings is an effective method. Select a healthy stem four to six inches long, cutting just below a leaf node. Remove leaves from the bottom two inches of the cutting to expose nodes, as these are where new roots will emerge. Cuttings from mature, vigorous stems increase the likelihood of successful rooting.
Cuttings can be rooted in water or a moist potting mix. For water rooting, place the cutting in a glass, ensuring nodes are submerged, and change the water every few days. For soil rooting, insert the cutting into a small pot with well-draining, moist potting mix. A warm, bright location with consistent moisture encourages root development within a few weeks.
Troubleshooting Common Issues
Purple passion plants can exhibit leggy growth, characterized by long, sparse stems, often due to insufficient light. Moving the plant to a brighter location with indirect light can promote more compact and bushier growth. Loss of the plant’s characteristic purple color, resulting in greener leaves, also indicates a lack of adequate light. Increasing light intensity, without direct harsh sun, can restore vibrant coloration.
Crispy or browning leaf edges often signal underwatering or low humidity. Regularly checking soil moisture and adjusting watering frequency can resolve this issue. If the air is dry, increasing ambient humidity can also help. Conversely, yellowing leaves, particularly lower leaves, often point to overwatering, where the roots are sitting in saturated soil.
Common houseplant pests, such as spider mites, mealybugs, or aphids, can affect purple passion plants. Inspecting the undersides of leaves and stem joints regularly helps in early detection. If pests are present, gently wiping affected areas with a damp cloth or a cotton swab dipped in rubbing alcohol can control minor infestations. For persistent issues, use an insecticidal soap formulated for houseplants.
