Purple Passion Plant Care
Size & Growth
Royal Velvet Plant grows to a height of 1′ or 2′ feet and has a spread of 2′ to 4′ feet.
The foliage is the main attraction for Purple Velvet.
As the name suggests, the evergreen leaves are covered with velvety, purple hair.
The leaves may grow to be 8″ inches long and may be either elliptical or oval.
They are coarsely toothed along the edges and dark green in color.
As individual leaves age and grow larger, the hairs spread, and the purple appearance diminishes.
Flowering & Fragrance
This winter-blooming plant produces clusters of tiny, showy orange and yellow flowers in the wintertime, from November to February.
Plants grown in lower light tend to bloom less.
Although the flowers are lovely to look at, many people remove them when they appear because they do not smell good.
Furthermore, they create a great deal of litter.
Light & Temperature
The foliage color is most attractive when the Purple Passion Plant is kept in bright, filtered sunlight.
Direct sunlight will damage the leaves.
Brighter light results in deeper, more intense shades of purple.
The best temperature for Purple Velvet Plants is a comfortable room temperature ranging between 60° and 70° degrees Fahrenheit (15° – 21° C).
Purple Passion Plant is winter hardy in USDA hardiness zones 10 through 12.
Watering & Feeding
Moderate watering is advised.
Keep the soil slightly moist at all times, but do not overwater.
Purple Velvet’s roots are quite sensitive and will rot easily.
Water from below, and avoid getting the leaves wet because moisture can become trapped in the hairy leaves and cause leaf and stem rot.
These plants are heavy feeders and may be fertilized as often as once a week with a 50% solution of a good quality water-soluble houseplant fertilizer throughout the growing season (spring through fall).
In the wintertime, you should fertilize once a month.
Soil & Transplanting
Use a rich, soil-based potting mix which both retains moisture and provides good drainage.
Be careful not to over pot.
Purple Velvet does well root bound and will appreciate being kept in a smaller pot.
When you do repot, just go up to the next size.
Grooming & Maintenance
Trim and pinch back the tips of the plant stems to prevent a leggy appearance.
You may occasionally need to provide a heavy pruning.
Be sure to save the cuttings for propagation.
How To Propagate Gynura Aurantiaca
Cuttings may be rooted in water or vermiculite or perlite.
When roots appear, transfer your new plants to their permanent pots and treat them as mature plants.
Gynura Aurantiaca Pest or Disease Problems
With the right amount of water, light, and ventilation, you should not experience any problems.

Low lighting may cause leaves to lose their purple hue and appear entirely green.
