Hoya Carnosa Variegata: Variegated Wax Plant Care

The variegated wax plant (botanically known as the Hoya carnosa ‘Variegata’) is a tropical plant that is popular for its attractive variegated leaves.

Depending on the particular variety, the leaves are a mixture of green, white, cream, and pink.

This plant is great in hanging baskets and can be used as a houseplant indoors or outdoors.

In this article, we will give a little background on what Hoya carnosa variegata plants are and discuss the best way to care for them.

What are Hoya Carnosa Variegata Plants?

A Hoya carnosa plant is a semi-woody succulent vine that is often called a wax plant, wax vine, honey plant, or porcelain flower plant.

There are varieties of the Hoya carnosa plant family that have variegated leaves.

Variegation means that the leaves display various colors and hues, particularly as uneven patches or streaks.

Like the original non-variegated Hoya carnosa plant, the variegated wax plant also blooms with waxy umbel-like clusters of sweetly scented flowers.

What Are Hoya Carnosa Variegata Plants

Origins of the Hoya Carnosa Variegata Plant

Hoya carnosa, native to Australia, Southeast Asia, Southern India, and parts of the tropical Far East, is now a global treasure.

In the late 18th and early 19th centuries, many botanists went on voyages of discovery to find new plants in far-off lands. 

Robert Brown was a Scottish botanist who traveled to Australia in December 1801.

He undertook extensive research and collected about 3,400 species of plants, more than half of which he named and which were previously unknown.

Hoya carnosa, which he named after his friend and colleague, Thomas Hoy, was one of these. 

The original Hoya carnosa was hugely popular in the 1970s and has recently made a comeback. 

Different Types of Hoya Carnosa Variegata

Amongst the variegated wax plants, the most popular variegated versions are the Tricolors, Krimson Queen, and Krimson Princess, as well as the Purple Pride cultivars.

Note that all these variations are often referred to as Hoya carnosa variegata tricolor plants.

Hoya Carnosa cv. Krimson Queen (Tricolor)

Hoya Carnosa Cv. Krimson Queen

Hoya carnosa cv. Krimson Queen, (also known as the Hoya Carnosa cv. Tricolor), has leaves that are green with white margins.

They also sprout pink leaves at times. Side note: the acronym “cv.” means cultivar.

Hoya Carnosa cv. Krimson Princess (Tricolor)

Hoya Carnosa Cv. Krimson Princess

Hoya carnosa cv. The Krimson Princessis another variegated cultivar that is often confused with the Krimson Queen.

The difference is that the leaves are cream-colored leaves that have a green border and variegations concentrated in the center.

The Krimson Princess is also considered a ‘Tricolor Hoya’ as the colors of the leaves come in cream to a yellowish hue, green, and light to dark pink.

When the plant is young, the new leaves often start out a cheerful bright pink.

Hoya Krimson Queen versus Krimson Princess 

The biggest difference is the color of the leaves. The Krimson Queen has green variegated leaves with white edges, while the Krimson Princess is the opposite, with cream variegated leaves that have green edges.

Both have the occasional pink leaf in the mix as well.

The similarities are the flowers. They produce flowers, which are mauve and star-shaped with a mauve corona that has a hot-pink center and is arranged in clusters.

Like all Hoya carnosa plants, they smell beautifully sweet.

Each flower measures about three-quarters of an inch in diameter, and there are about 20 to 25 of them in each cluster. 

Hoya Carnosa ‘Purple Pride’

Another popular variegated wax plant is the Hoya Carnosa cv. Purple Pride.

This variation has slightly smaller star-shaped flowers with a plum-colored corona in the center.

It has more florets (about 30) in each cluster. Its fragrance is light and sweet. 

Variegated Wax Plant Care

Hoya carnosa variegata is a common house plant, though in tropical and some subtropical environments it thrives outdoors when planted directly in the soil or in a hanging basket.

Just make sure it’s in a location that has bright indirect light. Below are some basic care guidelines to follow so that your variegated wax plant will thrive.

Light

Whether you grow these intriguing plants indoors or in your garden, they’re going to need bright, indirect light conditions. 

Some direct sunlight is fine, but make sure they don’t get more than 2 to 3 hours because excessive sun exposure may burn or yellow their leaves.

Temperature

Temperature for Variegated Wax Plant

Indoors, these plants thrive when the temperature is between 70 and 75 degrees Fahrenheit during the day and no lower than 60 to 65 degrees Fahrenheit at night.

In winter, when they aren’t growing, they’ll survive in temperatures as low as 40 degrees Fahrenheit.

They do particularly well indoors if the relative humidity is around 30–40%. 

Water Regularly

When the soil in your variegated Hoya plants container feels dry to the touch—insert your finger 1 to 2 inches into the soil—it is time to water the plant.

Slowly saturate the soil with water until it runs out of the bottom of the container through the drainage holes.

Depending on the season, you may need to water the plant once or twice each week in the spring and summer and less so in the fall and winter.

Just make sure to follow the rule of thumb of letting the soil dry out a little before watering the plant again.

Remember, as with any other plant, overwatering will lead to many issues, like root rot.

Soil

Soil for Variegated Wax Plant

In its natural environment, Hoya carnosa variegata is epiphytic, growing naturally on trees and rocks for support.

It has a very shallow root system and won’t need deep or nutrient-rich soil to thrive in your garden. 

To allow your soil to drain, we usually recommend adding soil amendments like perlite or mixing some African violet potting soil to your potting soil mix.

Fertilizer

Hoya carnosa variegata, like the majority of houseplants, enjoys a little fertilizer.

Feed your Hoyas once every month with a diluted liquid fertilizer during the growing season.

Once cold weather arrives, reduce (or even stop) the amount of fertilizer used.

What we tend to use is this self-dissolving fertilizer.

Propagation

Variegated Hoya carnosa plants are easily propagated from stem cuttings.

The best time of year to propagate it is between mid-spring and mid-summer when the plant is actively growing.

There are two primary ways to propagate your variegated wax plant: soil propagation and water propagation.

Soil Propagation

Soil Propagation Variegated Wax Plant

Fill a pot with a well-draining potting mix. As soon as the soil is ready, you can begin propagating your variegated Hoya plant.

Begin with a clean and sterilized knife or pair of pruning shears. Remove one stem from your Hoya Krimson Princess plant.

Make an approximately 6-inch-cut and remove the leaves from the bottom quarter of the stem.

The stem should be healthy and have 2 to 3 leaves still attached. This is the portion of the stem that will produce roots.

If you have access to rooting hormone, we suggest you dip the ends of the cutting in some.

Rooting hormones will increase the chances of stem cutting to rooting.

Plant this end of the stem in the previously-prepared soil and, within 3 to 4 weeks, the stem cutting should have rooted.

Water Propagation

Water Propagation Variegated Wax Plant

Water propagation is a highly effective method for producing plants for free. Start by filling a jar with clean water.

Take your knife or a pair of shears to cut a stem cutting from your variegated hoya plant.

As with the soil propagation method, cut a stem to about 6 inches long.

Make sure the stem is a healthy one that has 2 to 3 leaves still on it. robust and have two to three leaves.

Place the stem cutting into the water and ensure that no leaves are below the water line.

Place the container in a location with a bright location.

Refresh the water as it becomes murky, and within 3 to 4 weeks, you should notice roots start sprouting.

Once roots have formed, transfer them to a pot with fresh potting soil.

Common Issues Growing Hoya Carnosa Variegata Plants

Frequent Issues With Hoya Carnosa Variegata Plants

Common problems associated with growing Hoya carnosa variegata plants include browning leaves, wilting leaves, dropping leaves, the absence of blooms, and the presence of pests and diseases.

Pests

Sap-sucking insects such as aphids, mealybugs, scale insects, and spider mites are susceptible to infesting your wax plant.

Typically, aphids are spotted near the flowers, whereas mealybugs occupy the leaves.

Immediately eradicate these pests if you spot them to prevent further plant harm.

Disease

Wax plants are susceptible to two common fungal illnesses, including botrytis blight. This causes the entire plant to rot, from the leaves to the roots.

Initial symptoms include wilting, black or brown stem lesions that are dry or mushy, and black or gray roots.

Other illnesses include the growth of black sooty mold on wax plant leaves. Aphids, mealybugs, and other sap-sucking insects are to blame.

The sooty mold rarely poses a threat to the wax plant’s vitality, but it can be eliminated by eliminating the pests.

Neem oil and insecticidal soap are straightforward remedies for this issue.
