Hoya linearis

Hoya Linearis

The Hoya linearis is a unique hoya with a very distinctive appearance. They are endemic to Southeast Asia and Australasia. Long fuzzy green stems support the wax plant's green needle-like leaves. As opposed to other Hoyas, these have pliable, slightly hairy leaves. As a result, these hoyas look like fuzzy green curtains spilling over their pot. After reaching a height of about 12 inches, the plant begins to spill out of its container. The tall stalks may reach heights of six or eight feet.

The plant is of a rare and unique variety that is difficult to track down. Many people struggle with Hoya linearis because of how difficult it is to care for. 

When it blooms, it can surprise you with up to 13 white star-shaped flowers. In addition, some coronas have a pinkish or yellowish-white hue. The blooms have a pleasant lemony scent.

How to care?

Hoya linearis

Hoya linearis requires the same care as other hoyas, with a few exceptions where temperature and humidity is concerned.


  • Low watering requirements
  • Temperature range 16-27 degrees C
  • Humidity range above 50%
  • Well-draining loose soil
  • Bright, indirect light

Hoya linearis Detail

Light Requirements:

  • It is recommended that you place this plant in a sunny window, preferably in the morning, and that you water it regularly. This plant will thrive in bright light, especially during the winter.
  • The sun can be dangerous if exposed to it for too long, so those who reside in warmer climates should take care. This hoya prefers a more temperate climate.
  • In the summer, your plant may benefit from some diffraction of the direct sunlight depending on its location. If your plant doesn't like what you're doing, it'll let you know.
  • Keep in mind that the potting medium for your Hoya linearis must dry out quickly, so making sure it gets enough light is essential.

Temperature Requirements:

  • This plant can survive in relatively cool evenings because it is a Hoya from a higher altitude. Make sure the temperature never drops below 15 degrees Fahrenheit (10C).
  • For optimal growth, daytime temperatures should be kept between 60 and 80 degrees Fahrenheit (16 and 27 degrees Celsius).
  • Indoor hoyas should not be exposed to temperatures below 55 degrees Fahrenheit at night.

Humidity Requirements:

  • Although Hoya linearis thrives in more humid conditions,  the typical humidity found inside a home is fine for it.
  • In the dry winter months, however, do use my humidifier. Your plant will thrive with humidity levels of at least 50%. 
  • Keep in mind that misting does NOT increase the air's humidity, but as an epiphyte, this plant will benefit from misting anyway. 

Watering Requirements:

  • When it comes to Hoya linearis, if you keep the soil on the dry side (but still water regularly), these plants will thrive. These hoyas, like all hoyas, thrive when given long periods of dryness between waterings.
  • When watering, the potting medium should be soaked thoroughly. Wet the soil thoroughly, to the point where water runs freely through the drainage hole.
  • Like other hoyas, they do best when allowed to dry out between waterings. Don't water again until all of the potting soil has dried out.
  • You can use your finger to feel the potting soil to determine when it is dry. Try picking up the pot and gauging its lightness. When the soil is completely dry, you will notice it.
  • Stress symptoms are something to keep an eye out for. If the plant experiences too much stress, it may dry out or wither.

Soil Requirements:

  • A potting mix that is light and airy is ideal for growing plants. Hoya linearis, or any hoya for that matter, can be treated with a number of different methods.
  • This plant would thrive in a succulent or cactus mix to which perlite has been added. Keep in mind that any plant, but especially epiphytes, benefits from rapid drainage.
  • A good mixture for epiphytic plants in general (but not moth orchids!) is 2 parts soilless mix to 1 part fine-grain bark mix, as recommended by Horticulture magazine. 
  • Perlite can be used as a substitute for fine-grain bark mix if you can't find any. To a good cactus/succulent potting mix, add perlite. To find out what works best for you, try different things.

Fertilizing Requirements:

  • Use a well-balanced, all purpose fertilizer, diluted to half strength with water. 
  • Where possible, do use organic fertilizers. Chemical fertilizer cause chemical build-up that can affect the soil’s permeability and cause the leaves to burn. 
  • Fertilize your hoya once a month during the growing season, but do not fertilize when the plant is dormant.
