Hoya carnosa 'Krimson Queen'

Hoya Carnosa 'Krimson Queen'

Hoya carnosa has many variegated cultivars, among which is the Hoya carnosa 'Krimson Queen'. This variegated cultivar is also known as Hoya carnosa 'Tricolor', Hoya carnosa (Variegata), or just Hoya 'Krimson Queen'.

This climbing plant is indigenous to Southeast Asia and Australia and is best used for ornamental purposes. Indeed, Hoya carnosas will elegantly adorn your home in hanging baskets because they are epiphytic (meaning they grow upon trees and other supports).

H. vcarnosa 'Krimson Queen' has leaves with pink and white edges that are variegated. These heart-shaped leaves can reach a length of 5 cm and are smooth and waxy. 


The inflorescence consists of a number of dangling or more upright flowers arranged in an umbel. Although they can range from near-white to dark pink, the blossoms are often light pink. They appear to be composed of wax and are born in clusters with a star-like shape. The surface of the flower has a fuzzy appearance due to the microscopic hairs that cover it. They may produce extra nectar that drops from the petals and have strong scents.

Hoya carnosa blooms from spurs, just like all other Hoya species. These emerge from the axils of the leaves and stem; they may not bear flowers at first, but eventually, buds will appear from the tips of the spurs. These same spurs generate new flowers every season. Therefore, they shouldn’t be harmed or taken away.

The plant blooms from spring to late summer; on the same peduncle, it can produce umbels of 10 to 50 tiny star-shaped flowers that develop gradually over the course of 2 to 3 weeks. Early in the evening is when the aroma is greatest.

How to care?

Hoya carnosa 'Krimson Queen'

If you provide Hoya carnosa 'Krimson Queen' with the strong indirect light that they require, they are low-maintenance indoor plants to grow. They do not need to be constantly watered, nor do they demand a high degree of humidity in the air. Since the leaves of the Hoya carnosa 'Krimson Queen' are waxy, and the plant itself is succulent, it will require very little water.


  • Bright, indirect light
  • Temperature range of 45-95 degrees F
  • Humidity level of 70% to 80%.
  • Well-draining loose soil
  • Low watering requirements

Hoya carnosa 'Krimson Queen' Detail

Light Requirements:

  • In order to cultivate proper growth and variegation, the H. carnosa 'Krimson Queen' needs bright light that is largely indirect or light that has been filtered. On the other hand, being exposed to some direct sunshine, particularly in the winter and spring, can be beneficial.
  • During these months, exposure to the sun's rays for approximately an hour can aid in stimulating blossoming. On the other hand, take care to protect the Hoya's leaves from direct exposure to harsh light during the hot summer days.
  •  If you plan to keep your Hoya outside during the warm weather months, you must ensure that it has access to plenty of protection from the sun's rays in the form of shade. 
  • One viable alternative is to suspend it in an area where it is shaded by a tree.

Temperature Requirements:

  • These carnosa varieties are the perfect indoor plant in many climates because they prefer moderate, reasonably steady temperatures between 60 and 90 degrees F. 
  • Try to avoid extremes, whether inside or outside. The plant can be harmed by prolonged exposure to temperatures below 45 °F or above 95 °F.
  •  Additionally, bear in mind that the H. carnosa 'Krimson Queen' is not tolerant to subfreezing conditions; therefore, on cold nights, it is preferable to bring them inside.

Humidity Requirements:

  • Tropical regions are renowned for having high levels of humidity. As a result, your H. carnosa 'Krimson Queen' will flourish in an environment with a humidity level of 70% to 80%.
  • Put your H. carnosa 'Krimson Queen' in the bathroom if you live in an area with little humidity.
  • Placing your plant on a pebble tray is an additional approach to raising the humidity levels in the area. Simply place a tray under the pot and fill it with water and a few rocks. That goal will be accomplished by the evaporation of water.
  • Your plants can also be grouped together in one location. The humidity will rise as a result of their perspiration. Use a humidifier if humidity levels fluctuate.

Watering Requirements:

  • H. carnosa 'Krimson Queens 'are able to weather dry spells thanks to the waxy, succulent-like appearance of their leaves. Because of this, they are more susceptible to damage when the water level is too high than when it is too low.
  • Before you may water the plants again, you have to wait until the top three inches of soil have completely lost their moisture. In the event that this does not occur, the mix will get saturated, and the roots will remain in the surplus water. As a direct consequence of this, your H. carnosa 'Krimson Queen' will eventually succumb to root rot and pass away.
  • It is recommended that you water your plant anywhere from once to three times per week. Indeed, it is safer to risk underwatering than overwatering.
  • In addition, you shouldn’t water your plant the same amount every week during the entire year. You need to water your plants more regularly throughout the summer when the temperatures are greater.
  • On the other hand, you should reduce the frequency during the months of winter and fall.

Soil Requirements:

  • Once more, drainage is the secret to happiness. Soil with good drainage is essential for hoya growth.
  • It is best to use a potting mixture with a chunky texture that contains components like perlite, peat moss, pumice, and orchid bark. 

  • African Violet Potting Mix is a great ready-to-use alternative. Other succulent-specific combinations may also be beneficial. These quick-draining mixtures encourage aeration to prevent root rot.

Fertilizing Requirements:

  • Your Hoyas don’t need to be fertilised. However, use an organic fertiliser if you decide to do so.
  • During growing seasons, you can use an organic fertiliser twice a month (spring and summer).
  • You should avoid fertilising in the fall and winter. During certain times, your plant won’t be growing and won’t require more fertilisers.
  • Make sure your fertiliser has both potassium and phosphorus when selecting it.
  • Root burn may result from synthetic fertilisers. Therefore, if you decide to utilise them, we advise fertilising just once a month while the plants are growing.
