Purple Passion Plant Care (Gynura aurantiaca)
Last Updated: March 2026
TL;DR
The purple passion plant (velvet plant) has deep green leaves covered in soft purple hairsthat give it an electric, velvety purple appearance. It's easy to grow: bright light intensifies the color, pinching keeps it bushy, and it roots from cuttings in under 2 weeks. The catch: its flowers smell terrible (pinch them off) and the plant declines after 2-3 years, so propagate regularly.
| Factor | Requirement |
|---|---|
| Botanical Name | Gynura aurantiaca |
| Light | Bright indirect — some direct morning sun boosts color |
| Watering | When top 1 inch of soil is dry — at soil level only |
| Humidity | Average — not fussy |
| Temperature | 60-75°F (15-24°C) |
| Soil | Well-draining standard potting mix |
| Toxicity | Non-toxic to cats and dogs |
The Purple Hair Secret
The striking purple color isn't in the leaf itself — it comes from dense purple trichomes (hairs) covering the green leaf surface. When light hits these hairs, the plant appears intensely purple. This is why light quality matters so much: bright light makes the purple pop, while dim conditions make the plant look plain green.
Young leaves at the growing tips have the densest purple hairs and the most vivid color. As leaves age, the hairs thin and the green underneath shows through more. Regular pinching encourages new growth, keeping the plant looking its most purple.
The Smelly Flower Problem
Purple passion plants produce small, bright orange daisy-like flowers — and they smell awful. The odor has been described as stale gym socks or rotting food. Most growers pinch off flower buds the moment they appear.
Flowering also signals the beginning of the plant's decline. Purple passion plants are naturally short-lived (2-3 years). Once flowering begins, the plant puts energy into reproduction and the foliage quality drops. Take stem cuttings to propagate replacements before this happens.
Common Mistakes to Avoid
- ✗Not enough light. The purple fades dramatically in dim conditions. Bright indirect light with some morning direct sun is ideal.
- ✗Watering on the leaves. Water trapped in the fuzzy hairs promotes rot and fungal spots. Always water at soil level.
- ✗Letting it flower. Pinch off buds to avoid the smell and extend the plant's productive life.
- ✗Not propagating. These plants decline after 2-3 years. Take cuttings annually to keep your supply going.

Frequently Asked Questions
Purple passion plant care requires bright indirect light, moderate watering (when top inch of soil is dry), and regular pinching to maintain bushy growth. The velvety purple hairs on the leaves give the plant its striking color. Bright light intensifies the purple — low light makes it appear greener.
Loss of purple color is caused by insufficient light. The purple hairs on the leaves are most vibrant in bright indirect light with some direct morning sun. Move the plant to a brighter location and new growth should come in with rich purple coloring. Older leaves naturally lose some color over time.
Yes — the small orange flowers have an unpleasant odor. Most growers pinch off flower buds as soon as they appear. Flowering also signals the plant is reaching the end of its life cycle. After flowering, the plant often declines. Take cuttings to propagate before this happens.
Purple passion plants propagate easily from stem cuttings. Take 4-inch cuttings, remove lower leaves, and place in water or moist soil. Roots develop in 1-2 weeks — one of the fastest-rooting houseplants. Since the parent plant declines after 2-3 years, regular propagation keeps your supply going.
Purple passion plants are non-toxic to cats and dogs. They are safe for pet-friendly households. The fuzzy texture of the leaves actually deters most pets from chewing on them.
