Hoya Krimson Queen Care Guide
Hoya Krimson Queen is a variegated cultivar of hoya carnosa with cream or white variegation on the outside edges of the leaves and green centers. New leaves often emerge pink or pale salmon before the cream and green tones develop. It is one of two commonly available variegated hoya carnosa cultivars, the other being Krimson Princess, which has the variegation pattern reversed: green edges with cream or white centers. The care profile for both is identical to standard hoya carnosa, with one important difference: the reduced chlorophyll in the variegated sections means they grow significantly more slowly and require brighter light to sustain the same photosynthetic rate.
Quick Reference
| Factor | Requirement |
|---|---|
| Light | Bright indirect light; more than standard hoya carnosa |
| Water | Allow mix to dry 75 percent down before watering |
| Humidity | 50 percent or above |
| Temperature | 18 to 27 degrees Celsius |
| Soil | Very well-draining: coir, perlite, orchid bark |
| Fertilizer | Balanced or phosphorus-leaning, monthly, spring through autumn |
| Pot | Slightly potbound; drainage holes essential |
| Toxicity | Non-toxic to cats and dogs |
Light and Variegation
Bright indirect light is essential for krimson queen, more so than for the standard green carnosa. In medium or lower light, the variegated areas reduce and the plant produces more green-dominant leaves as it attempts to maximize chlorophyll. New growth may emerge with less cream than established leaves if light is insufficient. A position close to a bright south or west-facing window maintains the cream-to-green ratio consistently.
Watering, Potting, and Growth Rate
The same infrequent watering and very well-draining mix that suits standard hoya carnosa applies here. Allow the mix to dry significantly before watering. Because krimson queen grows more slowly than the green form, it uses water more slowly as well, so the interval between waterings is often longer. Check the mix rather than watering on a schedule. Keep the plant slightly potbound. Repot only when roots are clearly emerging from the drainage holes, moving up by one pot size.
Flowering
Krimson queen flowers from the same peduncles as standard hoya carnosa, producing the same clusters of fragrant, star-shaped flowers. The flowering triggers, including light level, root restriction, and seasonal temperature variation, are the same as for all hoyas and are covered in the how to get hoya to flower guide.
