Characteristics of Hoya Undulata

Hoya undulata, also known as the wax plant or porcelain flower, is a popular house plant that belongs to the Hoya genus. It is native to the Kalimantan region of Borneo and is renowned for its distinctive foliage and beautiful flowers. The leaves of hoya undulata are lance-shaped and can range in color from olive green to deep burgundy. They are rigid in nature and have undulating margins, giving the plant its unique charm. Additionally, the leaves are splashed with shimmery pink variegation, adding a touch of glamour to this already mesmerizing plant.

Care Instructions for Hoya Undulata

While hoya undulata is a stunning plant, it does require specific care instructions to thrive. Here are some essential requirements to keep in mind:


Hoya undulata prefers bright, indirect light for around 8 hours a day. It can tolerate partial shade but thrives in sunlight, where its foliage turns a deep purple color. However, direct sunlight should be avoided as it can scorch the leaves.


The ideal temperature range for hoya undulata is around 73-77°F (23-25°C) during spring and summer. In autumn and winter, the plant can be kept in a cooler spot at 59-61°F (15-16°C). It can tolerate slight temperature fluctuations but may shed leaves due to sudden changes.


Hoya undulata prefers moderate humidity levels of around 50%. While it doesn’t require frequent spraying, occasional leaf and stem washing with warm water can help remove dust and prevent pest infestations.


Moderate and regular watering is essential for hoya undulata. During the active growth period in spring and summer, the plant should be watered every 3-4 days. In the colder season, watering once every two weeks is sufficient. Always make sure to use settled water at room temperature to avoid shock.


Use mineral complex fertilizers designed for cacti and succulents. Apply the fertilizer every three weeks from early spring to early autumn. It’s best to combine fertilizing with watering to aid nutrient absorption and prevent root burning.


Pruning should be done sparingly with hoya undulata, as the plant is not tolerant of excessive pruning. Only remove yellowed, dried, or infected parts using a sharp and sterile instrument. Pruning can be done in late winter or early spring to maintain the desired shape.


Hoya undulata should be transplanted after three weeks of quarantine if newly purchased. Use a slightly larger container than the previous one, ensuring it has drainage holes for proper water management. Opt for a light and nutritious soil mixture, and water the plant after transplanting. Repotting every three years helps prevent root crowding and allows for healthy growth.

Propagation Methods for Hoya Undulata

Propagating hoya undulata can be challenging but rewarding. The most common method is through stem cuttings. Here’s an overview of the propagation process:

  1. Select a healthy stem of hoya undulata that is 4-5 inches long.
  2. Using a sharp knife or scissors, cut the stem near the mother plant.
  3. Remove the leaves from the bottom of the stem.
  4. Optionally, dip the cut end of the stem in rooting hormone to encourage root development.
  5. Place the stem in well-drained potting mix or a glass of water.
  6. If using soil, ensure it is moist before planting the stem. If using water, change the water every 2-3 days to prevent rotting.
  7. Once roots start to form, transfer the stem into a pot filled with a well-draining soil mixture.
  8. Keep the potted stem in indirect light, avoiding direct sunlight.

Common Issues and Solutions for Hoya Undulata

Although hoya undulata is a resilient plant, it can face certain problems. Here are some common issues and their solutions:

  1. Leaf Browning: If the leaves of your hoya undulata start browning, it could be due to inadequate lighting or incorrect watering. Adjust the lighting conditions and ensure proper drainage to prevent overwatering.
  2. Leaf Wilting: Wilting leaves may indicate underwatering or root diseases. Increase watering frequency or examine the root system for any signs of rot or fungal infection.
  3. Leaf Loss: Leaf loss can occur due to overwatering, extreme temperature fluctuations, or inadequate lighting. Adjust the watering schedule, provide stable temperature conditions, and ensure sufficient but not direct sunlight exposure.
  4. Lack of Flowering: If your hoya undulata fails to bloom, it may be due to insufficient light or improper fertilizing. Ensure the plant receives adequate indirect light and follow a consistent fertilizing schedule during the growing season.
  5. Pest Infestations: Common pests that may affect hoya undulata include aphids, mealybugs, and scale insects. Treat infestations with an appropriate insecticide, ensuring thorough coverage of affected areas.

With proper care, hoya undulata can be a captivating addition to your indoor plant collection. Just remember to provide it with the right amount of light, temperature, water, and nutrients, and you’ll be rewarded with the beauty of its unique foliage and stunning flowers.
