Hoya Carnosa Krimson Queen vs Princess: How to Tell Them Apart and Help Each Thrive

Meet the Variegated Royals

If you’ve fallen for variegated Hoyas, chances are you’ve met the Hoya carnosa Krimson Queen and her close cousin, the Krimson Princess. Both are elegant, vining houseplants with glossy leaves splashed in creamy white and pink, both smell incredible when in bloom, and both are tough enough to forgive the occasional missed watering. But while they’re often confused (and frequently mislabeled), these two cultivars have clear differences. As a long-time Hoya collector, I’ve grown both for years on the same shelf and can confidently say: once you know what to look for, you’ll never mix them up again.

How to Tell Queen from Princess

The quickest way to identify them is to look at where the cream or white variegation sits on the leaf.

Krimson Queen: Variegation on the edges. Think green centers with creamy white (often pink-tinged) margins. A handy memory trick: “QuEEn = Edges.”
Krimson Princess: Variegation in the center. Cream or pinky centers with green margins. Another trick: “PrINcess = INside.”

Both can flush with beautiful pink on new growth, especially in brighter light. Queens occasionally throw all-white leaves on strong variegation streaks, while Princess may gift you creamy, almost glowing centers framed by deep green.

Gardener’s note: On my shelf, the Queen is a touch faster and steadier, likely thanks to her larger green center. The Princess is a smidge slower but offers those dreamy, sherbet-pink centers you can’t help but admire.

Names, Synonyms, and Why Labels Get Messy

Both plants are Hoya carnosa cultivars. You may see Krimson Queen sold as Hoya carnosa ‘Variegata’ or ‘Tricolor,’ and Krimson Princess sold as Hoya carnosa ‘Rubra.’ Nurseries sometimes swap these names, which is why learning the leaf pattern matters more than the tag.

Despite their visual differences, care for Krimson Queen and Krimson Princess is nearly identical. If you can keep one happy, you can grow the other with ease.

Light Requirements

Bright, indirect light is ideal. A few hours of soft morning sun works wonders.
Variegates need more light than solid green Hoyas to keep their color. Too little light leads to dull, greener leaves and sluggish growth.
Avoid harsh afternoon sun through hot windows, which can scorch the creamy variegation.

Watering Rhythm

Let the top half to two-thirds of the pot dry before watering again.
In winter or low light, extend the dry period. In bright, warm conditions, water a bit more frequently.
Err slightly dry over soggy. Hoyas store moisture in their leaves and dislike constantly wet roots.

Potting Mix and Pot Size

Use an airy, fast-draining mix: roughly 40% high-quality potting soil, 30% orchid bark or coco chips, 20% perlite or pumice, and 10% horticultural charcoal.
Choose a snug pot with good drainage. Hoyas bloom best a little root-bound.

Humidity and Temperature

Average home humidity (40–60%) is fine; 60%+ encourages lusher leaves and better blooms.
Comfortable temperatures between 60–85°F (16–29°C). Avoid prolonged dips below 55°F (13°C).

Fertilizing

Feed lightly during spring and summer with a balanced, dilute fertilizer (something near a 3-1-2 ratio works well) every 4–6 weeks.
Skip or reduce feeding in winter when growth slows.

Growth Speed and Habit: Which Is Faster?

Krimson Queen generally grows a bit faster because its green centers contain more chlorophyll. Krimson Princess, with variegation in the center, tends to be a touch slower and may be pickier about light. That said, both will happily trail, climb, or twine around a small trellis. I like to train mine up a hoop when I’m chasing flowers and let them cascade when I want full, lush foliage displays.

Color and Variegation Management

Maintain bright, indirect light to keep variegation bold. Dim conditions encourage more green.
If you see entirely green vines emerging, prune back to a variegated node to discourage reversion.
All-white leaves on a Queen look special but won’t photosynthesize. Don’t panic; the plant compensates with other leaves. If too many appear, increase light slightly and consider pruning a few to preserve plant energy.

Personal tip: My Queen gets a bright east window with a sheer curtain. That setup keeps her margins creamy and pink without leaf scorch. The Princess sits just a foot closer to the glass for that extra nudge of light to support her variegated centers.

Propagation Guide for Both

Take a vine cutting with 2–3 nodes and at least one healthy leaf. Cut just below a node.
Remove the lowest leaf and root in water, damp perlite, or a chunky mix. Keep warm (70–80°F) with steady, bright light.
Plant up once roots are a few inches long. Don’t over-pot; small is better.

Spring through early summer is prime time for fastest results.

Blooming Tips and Fragrance

Both Queen and Princess produce clusters of waxy, starry blooms with a sweet, often evening-heavy fragrance. Depending on conditions, nectar can bead on the blooms — a normal, sticky delight.

Keep them slightly pot-bound.
Increase light in spring; a bit of gentle morning sun helps.
Give a slight day/night temperature drop.
Do not remove peduncles (the little spurs). Blooms return to these year after year.

Common Problems and Easy Fixes

Scorched leaves: Move a few feet back from harsh sun or add a sheer curtain.
Mushy stems or leaves: Overwatering. Let the mix dry deeper, improve drainage, and check the roots for rot.
Yellowing leaves: Usually moisture stress or poor drainage. Reassess watering and soil texture.
Pests (mealybugs, spider mites, scale): Inspect regularly. Treat early with a spray of insecticidal soap or neem, and dab mealybugs with an alcohol-dipped cotton swab.

Which One Should You Choose?

If you’re new to variegated Hoyas, start with Krimson Queen. She’s a tad more forgiving, usually grows faster, and keeps her color well in bright, indirect light. If you’re ready for something slightly fussier but incredibly charming, pick Krimson Princess for those glowing center variegations and soft pink flushes. Of course, the honest gardener’s answer is: grow both and let them climb together for a stunning contrast.

Price, Availability, and Styling

Both are widely available, but local demand can make the Princess a bit pricier in some regions. For display, I love pairing a Queen in a white pot to highlight her creamy margins and a Princess in soft blush or terracotta to bring out her rosy centers. Hanging baskets, macramé, or small trellises all suit their growth.

Pet Safety Note

Hoya carnosa is generally considered non-toxic to cats and dogs, though ingestion of any plant can cause mild stomach upset. Place higher if you have nibblers.

Quick FAQ

Are Krimson Queen and Princess the same species? Yes. They’re cultivars of Hoya carnosa with different variegation patterns.
Which is easier? Krimson Queen, typically.
Why is my plant losing variegation? It likely needs more light. Move it brighter, but avoid harsh midday sun.
Can I put them outside? In warm seasons, yes, in bright shade or gentle morning sun only. Protect from cold and direct midday rays.

Final Thoughts

In the Krimson Queen vs Krimson Princess debate, there’s no wrong choice — only what makes your plant-loving heart happiest. The Queen brings bold, clean edges and quick growth; the Princess brings soft, romantic centers and painterly pinks. Treat them to bright, indirect light, a chunky, well-draining mix, and a sensible watering routine, and they’ll reward you with glossy vines, dreamy leaves, and perfumed blooms. If space allows, grow them side by side — it’s the prettiest royal rivalry you’ll ever host on a windowsill.
