What is the difference between Hoya Pubicalyx and gracilis?

The Hoya Pubicalyx and Hoya Gracilis are both beautiful houseplants that belong to the Hoya genus. While they may share some similarities, there are distinct differences between the two.

Appearance:
The Hoya Pubicalyx, also known as the Wax Plant, features longer leaves compared to the Hoya Gracilis. These leaves are usually pointed and have a bright emerald green color. On the other hand, the Hoya Gracilis has shorter, more rounded leaves with a similar vibrant green hue.

Growth Habit:
One noticeable difference between these two Hoyas is their growth habit. The Hoya Pubicalyx tends to grow taller and more vine-like, making it a great choice for hanging baskets or training along trellises. It can reach impressive lengths, cascading down from its container or climbing up a support structure. In contrast, the Hoya Gracilis has a more compact growth habit, making it ideal for smaller spaces or as a tabletop plant.

Flowering:
Both the Hoya Pubicalyx and Hoya Gracilis are known for their exquisite and fragrant flowers. However, the blooms of the Pubicalyx are often larger and more intricate, with star-shaped petals in shades of pink, red, or purple. The flowers of the Gracilis, while smaller, are equally beautiful, typically displaying a star-like shape and coming in hues of white or pale pink.

Caring for Hoya Pubicalyx and Gracilis:
When it comes to caring for these two Hoyas, they have similar requirements. They both prefer bright, indirect light, and can tolerate some periods of direct sunlight. It’s essential to allow the soil to dry out slightly between waterings to prevent overwatering, as both plants are susceptible to root rot. Additionally, they thrive in average to warm temperatures, with humidity levels around 50%.

Propagation:
Both the Hoya Pubicalyx and Gracilis can be propagated through stem cuttings. Select a healthy stem and cut it just below a node. Remove the lower leaves and place the cutting in a well-draining soil mix or water until roots develop. It is worth noting that the Pubicalyx tends to root more easily and quickly compared to the Gracilis.

Personal Experience:
I have had the pleasure of growing both the Hoya Pubicalyx and Hoya Gracilis in my own garden, and each has its unique charm. The Pubicalyx, with its long vines and large, colorful flowers, has been a showstopper in my hanging baskets. It adds a touch of tropical elegance and creates a stunning display when in bloom. On the other hand, the Gracilis has been an excellent choice for my tabletops, adding a pop of green without taking up too much space. Its compact growth habit and delicate flowers make it a delightful addition to any room.

While the Hoya Pubicalyx and Hoya Gracilis share some similarities, such as their waxy leaves and vibrant green color, there are noticeable differences in their appearance, growth habit, and flowering. Understanding these distinctions can help you choose the right Hoya for your specific needs and preferences. Whether you opt for the taller and more intricate blooms of the Pubicalyx or the compact and charming Gracilis, both plants will undoubtedly bring beauty and joy to your indoor garden.
