Description

Hoya pubicalyx, often called Wax Plant or Porcelain Flower, is a stunning and hardy vine known for its glossy, waxy leaves and clusters of star-shaped flowers. The flowers are small but highly fragrant, typically white or pink with darker centers, and they bloom in dense umbels that resemble miniature bouquets. This plant is native to Southeast Asia and thrives as a trailing vine, making it ideal for hanging baskets or as a climbing plant along trellises. Hoya pubicalyx is relatively easy to care for and is beloved for its low-maintenance nature, making it a popular choice for indoor gardeners. Its attractive foliage and fragrant blooms add a touch of elegance to any space.

Light requirements

Hoya pubicalyx prefers bright, indirect light but can tolerate some direct sunlight, especially in the morning. Too much direct sunlight may scorch its leaves, so it's best to place it in a spot with filtered light, such as near a window with a sheer curtain. It can also adapt to lower light conditions, though it may not flower as prolifically. A spot with 4 to 6 hours of indirect light per day is ideal for encouraging healthy growth and blooming.

Soil preferences, including pH and drainage

This plant thrives in well-draining, slightly acidic to neutral soil, with a pH between 6.0 and 7.0. It prefers a mix that is airy and allows water to flow through easily, such as a potting mix designed for succulents or orchids. A combination of peat, perlite, and orchid bark can be a good mix for providing the drainage Hoya pubicalyx needs. Make sure the pot has drainage holes to prevent water from sitting at the bottom.

Water needs

Hoya pubicalyx enjoys regular watering but prefers to dry out between waterings. During the growing season, water when the top inch of soil feels dry to the touch, ensuring the plant doesn’t sit in excess moisture. In the winter, when the plant enters a period of dormancy, reduce watering, as it requires less moisture. Overwatering can lead to root rot, so be sure to let the soil dry out between waterings to maintain a healthy balance.
