The term “purple ivy plant” describes various plants with distinct purple foliage and a vining or trailing growth habit. These plants are popular for their ornamental appeal, adding vibrant color to indoor spaces or outdoor gardens. Their unique appearance makes them sought-after additions for plant collections.
Understanding “Purple Ivy Plants”
The term “purple ivy” is a common name for several distinct plants with striking purple leaves and trailing growth, not a single botanical species. Two frequently associated plants are Gynura aurantiaca (Velvet Plant or Purple Passion Plant) and Tradescantia pallida (Purple Heart or Purple Spiderwort).
Gynura aurantiaca has deep purple leaves covered in fine, soft, velvet-like hairs, giving it a fuzzy appearance and vibrant color. Its ovate to lance-shaped leaves can reach 6 inches long. This plant typically grows upright and bushy when young, eventually developing trailing stems.
In contrast, Tradescantia pallida features smooth, fleshy, dark purple, lance-shaped leaves, sometimes with a silvery sheen. Its stems are thick and somewhat fragile. This plant is known for vigorous, trailing growth, making it popular for hanging baskets or as groundcover in warmer climates. Though both share the “purple ivy” moniker due to color and growth, their distinct leaf textures and forms allow for easy differentiation.
Caring for “Purple Ivy” Varieties
Caring for purple-leaved vining plants involves providing consistent conditions to maintain vibrant coloration and healthy growth. While specific needs vary slightly between species like Gynura aurantiaca and Tradescantia pallida, general guidelines apply to both. Establishing a routine for light, water, and soil helps these plants thrive.
Light
Both Gynura aurantiaca and Tradescantia pallida flourish in bright, indirect light. Sufficient light is crucial for intense purple coloration; without it, leaves may revert to green or become leggy. Direct, intense sunlight, especially harsh afternoon sun, can scorch delicate leaves, causing discoloration or browning. An east or south-facing window with filtered light is often ideal for indoor cultivation.
Watering
Proper watering prevents issues like root rot or wilting. Allow the top inch or two of soil to dry between waterings. Overwatering causes root rot, so proper drainage is paramount. During active growing seasons (spring and summer), more frequent watering may be necessary. Reduce watering in cooler fall and winter months when growth slows.
Soil and Potting
A well-draining soil mix is crucial for both Gynura aurantiaca and Tradescantia pallida to prevent waterlogging. A suitable potting mix often includes peat moss, perlite, or sand to enhance drainage and aeration. Gynura aurantiaca benefits from rich, slightly acidic soil (pH 6.0-6.5). Tradescantia pallida prefers neutral to slightly alkaline conditions. Pots must have drainage holes. Repotting is typically needed every one to two years, or when the plant becomes root-bound.
Temperature and Humidity
These plants prefer average room temperatures, typically 60°F to 75°F (15°C to 24°C). They do not tolerate extreme cold or sudden temperature fluctuations. While Tradescantia pallida adapts to moderate humidity, Gynura aurantiaca thrives in higher humidity, ideally 60% to 80%. Increase humidity with regular misting, a pebble tray, or a humidifier.
Fertilization
During their active growing season (spring and summer), both Gynura aurantiaca and Tradescantia pallida benefit from regular fertilization. Apply a balanced, water-soluble fertilizer, diluted to half strength, every two to four weeks. Avoid over-fertilization, which can cause leaf burn or leggy growth. Reduce or stop fertilization during the dormant winter period.
Pruning
Regular pruning benefits both Gynura aurantiaca and Tradescantia pallida by encouraging bushier growth and maintaining shape. Pinching back stem tips promotes branching and prevents legginess, especially for Tradescantia pallida. Remove yellow, damaged, or overly long stems to rejuvenate the plant. Pruning can be done throughout the growing season.
Propagating “Purple Ivy” Plants
Propagating purple ivy plants is straightforward, primarily through stem cuttings, ensuring new plants retain parent characteristics. Both Gynura aurantiaca and Tradescantia pallida readily root from stem cuttings.
To propagate, select a healthy 4-6 inch stem from the parent plant. Cut just below a leaf node, where new roots emerge. Remove leaves from the bottom inch or two of the cutting to prevent rotting.
Root cuttings in water or moist potting mix. For water rooting, submerge the leafless portion in water and place in indirect light; roots develop within weeks. For soil rooting, plant the cutting directly into well-draining potting mix, burying the node. Keep the soil consistently moist but not waterlogged. Rooting hormone can be applied, though it’s often unnecessary as these plants root easily. New growth indicates successful rooting; transplant young plants into larger pots.
Common Challenges and Solutions
Purple ivy plants are generally easy to care for but can encounter common issues. Recognizing symptoms and implementing timely solutions helps maintain their health and vibrant appearance, as most problems relate to environmental conditions or basic care.
Loss of purple color or vibrancy indicates insufficient light. Move the plant to a brighter location with indirect sunlight to restore rich purple hues. Leggy growth (long, stretched stems with sparse leaves) results from inadequate light or lack of pruning. Increase light exposure and consistently pinch back stem tips for a bushier, more compact form.
Leaf discoloration (yellowing or browning) stems from various factors. Yellowing leaves often signal overwatering and root rot; allow soil to dry between waterings and ensure good drainage. Browning or crispy leaf tips suggest underwatering or low humidity. Provide consistent moisture and increase ambient humidity to alleviate these symptoms. While relatively resistant, these plants can be affected by common houseplant pests like spider mites or mealybugs. Regular inspection and prompt treatment with organic solutions like neem oil or insecticidal soap effectively manage infestations.
Toxicity and Safety
Understanding purple ivy plant toxicity is important for households with pets or small children. Gynura aurantiaca (Purple Passion Plant) is generally considered non-toxic to humans and common household pets like dogs and cats. While ingestion is not recommended, severe reactions are not expected.
Tradescantia pallida (Purple Heart) can cause mild skin irritation in some individuals and dogs if sap contacts the skin. If ingested by pets, it may cause mild stomach upset (vomiting or diarrhea). To ensure safety, place both plant types out of reach of curious pets and young children. Wash hands thoroughly after handling to minimize potential irritation.
