Hoya rosita

Hoya Rosita

The Hoya rosita is a rare and beautiful hoya species. It is a cross between the Hoya wayetii and the Hoya tsangii. And what makes it so lovely is that it inherits the best qualities from both of its parents.

Long, ovate leaves with a maroon tinge on the leaf tips characterise the plant. These leaves also change from green to brownish-red when sun stressed, making them a sight to behold.

Hoya rosita produces reddish pink flowers that look like buds with bright yellow tips. Each delicate flower is perched on an umbrella-like formation known as an umbel, and the buds of each flower almost always open at the same time. In general, Hoya rositas take four to five years to bloom when given the appropriate care and environment.

The plant grows as a climber. This is how it appears in its natural habitat. Most houseplant owners, however, will display it in hanging baskets due to its trailing vines.

How to care for

Hoya rosita

Like other hoyas, Hoya rosita does well with bright indirect light, warm temperatures, semi arid conditions and well-draining soil with organic content.


  • Bright indirect light with a few hours of morning or evening sun.
  • Humidity 60% and above
  • Well-draining soil with organic additives
  • Temperature range between 65-85 degrees F
  • Organic fertilizer during growing season

Hoya rosita Detail

Light Requirements:

  • Hoya rosita can tolerate full sun, and most growers favour a slight amount of stress in order to bring out the plant's distinctive leaf colour change. However, overexposure poses a risk, as it can rapidly cause leaf burn
  • If you want your Hoya to live for a long time, place it in a location that receives bright indirect light. As the plant ages and matures, it will produce flowers consistently throughout the growing season.
  • Hoya rosita can certainly live indoors if it is properly cared for. A window facing east is ideal because it receives morning sunlight. Avoid placing it in low-light environments, as it is unlikely to bloom or remain healthy for long.
  • Rotating a Hoya rosita plant for even growth is unnecessary.

Temperature Requirements:

  • The ideal temperature range for growth is between 65 and 85 degrees Fahrenheit.
  • You can leave your Hoya outside even when winter arrives if you reside in temperate zones. If not, it is best to bring it inside until the threat of frost has passed.
  • To prevent chilly draughts, keep it away from open windows and main door entrances. The same holds true for spaces with air conditioning and those with furnaces or heaters.
  • Heating pads and warm lights can help your hoya survive the winter months.

Humidity Requirements:

  • Hoya rositas can tolerate the majority of indoor humidity levels, but they will grow more quickly when the humidity is above 60%. 
  • Use a cool mist humidifier, group your indoor plants together, or add pebble trays filled with water under them.
  • Do observe your hoya for any signs of yellowing leaves. This means that the hoya probably is stressed due to low humidity. 
  • Excess humidity can also cause leaf rot and attract pests. Therefore try to maintain ideal humidity levels to keep your plant healthy.

Watering Requirements:

  • The leaves of the Hoya rosita act similarly to succulents in that they store water for use later and in times of drought. You won't need to water them as frequently as your other plants because of this.
  • In general, it's preferable to underwater Hoya as opposed to overwatering them. It might be wiser to wait a few more days if you are reaching for the can while trying to remember the last time you watered it.
  • When it's time to water, pour until the drainage system is full. When it's hot out, drink more water; when it's cold and dormant, drink less.

Soil Requirements:

  • By starting with the right soil, you can give your Hoya the best chance of succeeding. Both H. rosita and the majority of Hoya varieties dislike having their roots wet for an extended period of time.
  • As a result, you should have a bed or container with enough drainage holes as well as a lightweight, well-draining soil medium.
  • Owners of Hoya rosita plants should add perlite or a cactus and succulent mix to their potting soil to improve air circulation. To give the soil texture and prevent compaction, you can also add charcoal or compost.

Fertilizing Requirements:

  • A general-purpose fertiliser is the best kind to use on a Hoya Rosita. As long as the hybrid plant receives nutrients, fertiliser isn't a big deal.
  • Hoyas are light feeders, so you should probably give them doses at half strength and spaced out over a long period of time. Since doing so could harm the H. rosita's roots, you wouldn't want to go overboard.
  • During its growing season, which is from spring to mid-fall, only apply balanced liquid or solid fertiliser on a monthly basis. It is advised to choose a bloom booster over the standard variety if you want to see more blooms.
