Hoya serpens

Hoya Serpens

Even when it is not in full bloom, the exotic Hoya serpens, also popularly known as the "Wax-flower Plant," is a sight to behold. This particular hoya features coin-shaped small leaves that are thick succulent, and have prominent veins. Occasionally, the leaves feature small silvery splotches and have a velvety feel to them. 

This perennial species belongs to the Apocynaceae family, which is pronounced a-pos-ih-NAY-see-ee. Fortunately, taking care of the Hoya serpens plant is not as challenging as pronouncing its family name. It is a pretty plant with typical requirements for plants.

The Himalayan regions are where the Hoya serpens originates. It can be found in a number of Asian nations, including Indonesia, Malaysia, and Thailand. Over 200 species have been identified since Joseph Dalton Hooker made his initial observations of it in the 1880s.

The Hoya serpens produces unique pale green flowers with a sweet, hazy scent. However, when several flowers are blooming at once, their scent is more potent.

How to care for

Hoya serpens

The Hoya serpens plant requires average watering and thrives in bright, dappled sunlight. It enjoys every bit of humidity it can get, as well as being watered every other day. This hardy Serpens plant can withstand a wide range of temperatures and thrives in well-draining soil mixtures.


  • High humidity is essential, over 60% is a must!
  • Water deeply once the top 2 inches of soil is dry;
  • Grow indoors for sufficient warmth; choose a bright spot with at least 6 hours of dappled light. Southwest or East-facing windowsills are optimal;
  • To encourage blooming, ensure your plant gets sufficient light, and allow your Hoya Serpens to get slightly root bound;
  • Fertilize sparingly, and use phosphorous-heavy fertilizer to promote flowering. Don’t cut off the peduncles!

Hoya serpens Detail

Light Requirements:

  • For healthy growth, place your Hoya serpens plant in direct, bright sunlight. If indoors, you can put the serpens plant next to a window that faces the southwest or right inside the balcony door. Make sure that the plant is not exposed to direct UV rays as this could result in scorched leaves.
  • Place the Hoya serpens in partial shade if you have it potted outside. If you believe the sun's rays are too intense for it to handle, move it.
  • Permit the plant to spend 4 to 6 hours per day soaking up the full indirect sunlight. The Hoya serpens plant can also be grown under artificial lighting.

Temperature Requirements:

  • The ideal temperature range for this exotic houseplant is between 60 and 86 degrees Fahrenheit (15 to 30 degrees Celsius). 
  • The Hoya serpens plant prefers temperatures between 68 and 85 degrees Fahrenheit during the day (20 to 29 degrees Celsius). And it enjoys a temperature range of 54 to 64 degrees Fahrenheit at night (12 to 18 degrees Celsius).
  • Chill damage can result from temperatures as low as 50°F (10°C). Place your hoya on a heating pad should temperatures dip.
  • Temperature changes do not affect the Hoya serpens well. So, if placed next to a window, be sure it doesn't get direct, chilly wind draughts.
  • The same is true for direct airflow from heaters and air conditioners, which will have negative outcomes.

Humidity Requirements:

  • The fact that these Himalayan natives enjoy humidity should not come as a surprise. The Hoya serpens prefer humidity levels between 60% and 100%, which falls within the moderate to high range.
  • Use of a humidifier, which will assist in maintaining the desired humidity, is one method. As an alternative, you can keep your Hoya serpens plant in a glass container with a humidifier to keep the air humid and moist. In addition, misting the air around the H. serpens plant will aid it in absorbing more moisture.
  • Make sure that the humidity levels do not rise above what is necessary because a plant that is overly wet is much more susceptible to illness and infection.

Watering Requirements:

  • The H. serpens plant requires regular watering, but not on a daily basis. 
  • The roots of your H. serpens plant could perish if your potting mixture has a tendency to retain a lot of water, as is the case with overly peaty mixtures. Let the soil of the plant serve as your best watering guide. When it appears to be too dry, water it; when it is sufficiently moist, don't water it.
  • You should check the water content of the soil every other day. It's time to add some water if the top third or half seems dry. The Hoya serpens watering requirements are largely influenced by its environment and geographic location.
  • The frequency of watering should increase as the day becomes more sunny. Water your Hoya serpens 2–3 times per week, depending on the soil, if it is situated in a bright, sunny area. On the other hand, you should water your Serpens plant less frequently if it is in a humid environment.

Soil Requirements:

  • The Hoya serpens plant prefers to grow in pots made of coarse, well-draining soil. Make sure the soil is not too wet or dry because these conditions can cause the roots to rot or dry out quickly, respectively. For this wax plant, a pH of 6.0 to 7.0 is ideal (slightly acidic to neutral).
  • Coconut chips or a peat soil mixture are ideal for growing this perennial beauty. I suggest making a potting mixture with an equal mixture of peat, perlite, and orchid (fir bark, charcoal, and perlite).
  • As an alternative, you can combine two parts of the soilless medium with some fine-grained bark. Make sure the container or pot has drainage holes in the bottom if you plan to plant the Serpens plant in one. Eliminate obstructions to promote efficient airflow and drainage.

Fertilizing Requirements:

  • It is advised to fertilise your H. serpens plant with a high-quality fertiliser twice weekly or once per month. 
  • The best fertiliser to use is one that is slightly higher in phosphorous and is either organic or synthetic. The H. serpens plant will probably benefit from the increased phosphorous content as it grows.
  • Another choice is liquid fertiliser, which ideally has a 2:1:2 or 3:1:2 ratio. Use this once a week, and place it close to the stem of the Serpens plant. You can also use a fertiliser with a slow release. For better absorption, please apply the fertiliser to moist soil.
  • Don't overfeed your Hoya serpens plant as it could suffer from chemical burn.
