Hoya wibergiae

Hoya Wibergiae

Hoya wibergiae is one of the rarest species of Hoyas, and it has exquisite leaves and tiny flowers. The stunning forests of Indonesia, India, and the Maldives are home to their native species. 

It has waxy leaves that look rich and change appearance with the seasons and time. The plant is charming because of the silvery linings and splotches on its lush green leaves. If the silver gets enough sunlight, it starts to glow pink or turn a light purple. It's fascinating to see the wide variety of colours and the detailed patterns on the leaves. This plant has fragrant inflorescences that can bloom twice a year, like all Hoyas. These come in clusters of up to 70 flowers, each with a tiny star shape, cream corollas, and a rosy centre.

How to care for

Hoya wibergiae

It's not too difficult to care for this plant if you're a beginner. Hoya wibergiae thrives in bright, indirect light and appreciates routine watering. If you use a well-drained soil mixture with substrates like peat moss and perlite, it encourages optimum growth.


  • Temperature range from 78 and 82 degrees Fahrenheit
  • The average humidity level of 50%.
  • Less watering
  • Bright indirect light with few hours of direct sun, either morning or evening sunlight
  • Well-draining soil with organic content
  • Organic fertilizing during the growing season

Hoya wibergiae Detail

Light Requirements:

  • Hoya wibergiae thrives in bright indirect light. Too little or too much sunlight will cause the waxy plant's surface to scorch or become dehydrated.
  • Since it blooms, you should place the flowering plant where bright light is visible from a distance, especially during the blooming season. The light's light particles encourage the plant's growth by enhancing photosynthesis.
  • If you have curtains, putting the pot on the windowsill will be a great idea. You can close them at noon and reopen them at dusk.
  • When Hoya wibergiae receives adequate sunlight,  the silver splotches in the leaves acquire a pink and dusky purple coloration, which enhances the appearance of the leaves.

Temperature Requirements:

  • Although Hoya wibergiae prefers moderate temperatures, it is more tolerant of heat than cold.
  • It does best at 78 to 82 degrees Fahrenheit, which is moderate (25.5 to 27.7 degrees Celsius). You only need to take additional precautions to maintain the temperature if you live in an area with an extreme climate.
  • If the plant receives some filtered sunlight during the summer's peak months of June and July, keeping it indoors and constantly hydrated will shield it from the elements.
  • In contrast, if you have a waxy plant during the winter months of November and December, you should exercise caution, especially if it snows where you live. I never leave it outside during the winter because it gets icy and the temperature drops below 60 degrees Fahrenheit (15.5 degrees Celsius).
  • Its sustainability is hampered by the freezing of the cells caused by the extreme cold. Bring your Hoya inside right away and leave it there for a while if you notice drooping and discoloured leaves.

Humidity Requirements:

  • Hoya wibergiae has low humidity requirements in addition to its water needs. Although it thrives in average humidity, giving it more will promote optimum growth.
  • The plant grows more robust and healthy when the humidity is kept at 60% or higher.
  • Use humidity domes, pebble trays and humidifiers to maintain humidity levels.

Watering Requirements:

  • Although this species of Hoya doesn't need a lot of water, a moderate amount is essential for its well-being. Hoya wibergiae can naturally retain some moisture because it is waxy and succulent. A sufficient supply of water is necessary because it aids in photosynthesis, nutrient transport, and nutrient absorption by the plant.
  • Although you are not required to follow a strict schedule, it is best to water your plant frequently. Three times a week, preferably in the morning, is when I prefer to water my Hoya wibergiae. It encourages growth while protecting the roots.
  • Your Hoya will require a little more water during the summer because of the increased evaporation and transpiration brought on by the warmer air. A workable solution would be to water every other day to replace the frequently lost moisture.
  • Furthermore, you should mist the plant with warm water if you notice that its lovely leaves are becoming brittle to the touch.

Soil Requirements:

  • A soil mixture that does not retain too much water and promotes airflow is necessary for Hoya wibergiae. It is necessary because excessive water that collects around the roots over time may cause serious damage to them. Additionally, waterlogging encourages fungi and other microbes that lead to root rot.
  • This is why well-drained soil performs well. It is best to prepare it yourself even though you can purchase it because it is crucial to add the correct combination of ingredients for each plant. peat moss, perlite, and fine orchid bark are all good additives for Hoya wibergiae.
  • For best results, add a small amount of coconut coir and charcoal. By including a few pieces of coconut coir, which aids in retaining moisture, you can prevent dehydration caused by other ingredients from happening to your Hoya.
  • In addition to the soil mixture, you should maintain a neutral pH for your plant, which may be slightly acidic (6-7). Nutrient availability is aided, and the mild acidity deters bacteria without endangering the plant.

Fertilizing Requirements:

  • Hoya wibergiae typically doesn't require external feeding and can grow just fine on its own. It is a flowering plant, though, so a little assistance during the blooming season can go a long way.
  • For the best growth of its flowers and leaves, this species needs a significant amount of phosphorus, even though the soil also needs other nutrients like potassium and nitrogen.
  • A well-balanced fertiliser is also a great idea because it makes up for any deficiencies in the soil, but keep in mind to choose one with a higher Phosphorus ratio.
  • It is recommended to use liquid fertilizer because it is simple to add some water and spray it on the leaves.
