Looking for the passionflower vine (Passiflora) or edible passion fruit? This guide is about the velvet houseplant Gynura aurantiaca.
Few houseplants stop people in their tracks like the purple passion plant. Its green leaves are cloaked in fine reddish purple hairs that catch the light like velvet, and the whole plant seems to glow violet. The good news: purple passion plant care is genuinely beginner-friendly. The catch: there are two quirks keeping the purple vivid, and never misting it—that trip up most new owners. Here’s everything you need.
What Is a Purple Passion Plant?
The purple passion plant is Gynura aurantiaca, an evergreen trailing perennial in the daisy family (Asteraceae), native to Southeast Asia and Java, Indonesia. It also goes by velvet plant, purple velvet plant, royal velvet plant, and purple passion vine. Its signature feature is the coat of reddish-purple hairs (trichomes) covering its green leaves and stems, giving it that unmistakable velvety sheen. According to the North Carolina State Extension, it’s commonly grown as a houseplant and is best displayed in a hanging basket, where its sprawling stems can trail. The Missouri Botanical Garden notes the popular ‘Purple Passion’ is a trailing cultivar prized for exactly this habit.

Light: The Secret to Keeping It Purple
Light is the single biggest factor in how purple your plant stays. Purple passion plants thrive in bright, indirect light, ideally near an east- or south-facing window with protection from scorching afternoon sun. Here’s the key: in low light, the plant survives but its vivid purple fades back to plain green, and it grows leggy reaching for the window. If you don’t have a bright enough spot, a grow light works well — see our guide to the best grow lights for indoor plants. Avoid harsh direct midday sun, though, which can scorch the delicate hairy leaves.
Watering Without Rot
Purple passion plants need consistently moist — never soggy — soil. Water thoroughly when the top inch of soil feels dry, and always let excess drain away. Overwatering is the fastest way to kill this plant, leading to root rot. A few rules:
- Water the soil, not the leaves. Pour directly onto the soil — the leaf hairs trap water and can rot if they stay wet.
- Cut back in winter, when growth slows and overwatering risk rises.
- Use a pot with drainage holes and never let it sit in a saucer of water.
Humidity & Temperature (Why You Must NOT Mist)
This is the counterintuitive rule that sets a healthy purple passion plant apart. It enjoys moderate humidity and average room temperatures of 60–75°F, kept away from cold drafts and heating vents. But unlike most humidity-loving houseplants, you should never mist it. Those velvety leaf hairs trap moisture against the surface, and that trapped water leads to rot and unsightly spotting. If your air is very dry, raise humidity with a nearby humidifier or a pebble tray instead — never a spray bottle.
Pro tip: this “no misting” rule is the opposite of what works for ferns and calatheas. When in doubt with a fuzzy-leaved plant, raise humidity around it, not on it.
Soil & Fertilizer
Purple passion plants want a well-draining, loam-based potting mix that holds some moisture without staying waterlogged. The Royal Horticultural Society recommends a peat-free, loam-based compost in bright, filtered light. Feed every 2–4 weeks during spring and summer with a balanced houseplant fertilizer, and reduce or stop in winter when growth slows. Detailed cultural requirements are well documented by UF/IFAS Extension. Don’t overfeed — it encourages weak, leggy growth.
Pruning & Keeping It Bushy
Pruning is essential, not optional, with this plant. Purple passion plants have weak, sprawling stems that grow leggy over time. The fix is simple: pinch back the growing tips regularly. This encourages branching, keeps the plant full and compact, and gives you cuttings to propagate. Do this through the growing season whenever stems start to stretch.
Should You Let It Flower?
Mature purple passion plants produce small clusters of orange-yellow flowers, usually in fall or winter. Here’s the surprise most owners aren’t prepared for: the flowers smell genuinely unpleasant — earning the plant its unaffectionate nickname, the “stinky feet plant.” Many growers pinch the buds off before they open, which also redirects the plant’s energy back into its colorful foliage. The flowers are harmless; whether you keep them is purely about the smell.
How to Propagate Purple Passion Plant
Propagation is the key to keeping this plant around, since its lifespan is only about 3–5 years. Luckily it roots almost effortlessly from stem cuttings:
- Take a cutting. Snip a 3–4 inch stem tip just below a leaf node — ideally one you’ve pinched off during pruning.
- Remove lower leaves. Strip the leaves from the bottom inch of the cutting.
- Root it. Place the cutting in water or moist, well-draining potting mix.
- Wait for roots. Roots typically form within a couple of weeks; keep it warm and in bright, indirect light.
- Pot it up. Once roots are an inch or two long, plant water-rooted cuttings into soil.
Is the Purple Passion Plant Pet-Safe?
Yes — the purple passion plant is safe for pets. Gynura aurantiaca is classified as non-toxic to both cats and dogs by the ASPCA (listed under “Purple Velvet Plant” and “Velvet Plant”). You may see some blogs claim it’s toxic — that’s incorrect. As with any plant, a pet that eats a large amount may get a mild upset stomach, but this species carries no toxic principles. It’s a genuinely worry-free choice for pet households.
Common Problems
- Leaves turning green / losing purple: not enough light. Move to a brighter (indirect) spot.
- Leggy, sparse growth: low light and/or skipped pruning. Pinch tips and increase light.
- Yellowing, mushy stems: overwatering and possible root rot. Let it dry out and check drainage.
- Brown spots on leaves: often water sitting on the hairy leaves — water the soil only, never mist.
Frequently Asked Questions
How do you care for a purple passion plant?
Give it bright indirect light, water when the top inch of soil dries, keep it at 60–75°F with moderate humidity, never mist it, and pinch the stems to keep it bushy. Feed every 2–4 weeks in spring and summer.
Why is my purple passion plant losing its purple color?
It’s not getting enough light. In low light the purple hairs fade and the plant reverts to green. Move it to a brighter spot with bright, indirect light to restore the color.
Should I mist my purple passion plant?
No. The velvety leaf hairs trap water, which leads to rot and spotting. Raise humidity with a humidifier or pebble tray instead of misting.
Is the purple passion plant toxic to cats and dogs?
No. The ASPCA lists Gynura aurantiaca as non-toxic to both cats and dogs, making it a pet-safe houseplant.
How do you propagate a purple passion plant?
Take a 3–4 inch stem cutting below a node, remove the lower leaves, and root it in water or moist soil. Roots usually form within a couple of weeks.
Why does my purple passion plant smell bad?
Its orange-yellow flowers have an unpleasant odor — hence the nickname “stinky feet plant.” Many growers pinch off the flower buds to avoid the smell and keep energy in the foliage.
How long do purple passion plants live?
About 3–5 years. Because they decline with age, take stem cuttings while the plant is healthy so you always have a young, vibrant replacement.
