Hoya undulata is a rare and fascinating plant that was first discovered in Borneo's Kalimantan region in 2015. It thrives in the lowland heath forests at around 350 meters and is named for its uniquely undulating leaf margins. The corona lobes of its flowers possess two hooked appendages that are exclusive to this Hoya and Hoya griffithii.
Although it is notoriously challenging to cultivate, witnessing its stunning flowers is a reward in itself. The plant's lance-shaped leaves are firm and can range in color from olive green to deep burgundy, depending on the amount of light it receives. Additionally, the leaves are beautifully speckled with shimmery pink variegation. The flowers are large, star-shaped, porcelain white, and decorated with red speckles on the outer side of the petals.
Care Note:
Those who have attempted to import this item previously are well aware of its delicate nature. Not only are these plants hard to find, but ensuring they survive shipping can be a challenge. However, rest assured that these specimens are well-rooted. I strongly recommend repotting them only when you observe the roots emerging from the bottom of their container, as they are prone to stress and can wilt easily. Purchase them only if you're up for the challenge, for these unique plants can become a proud addition to your collection!
Recreate conditions under a tree canopy, where plants receive lots of light, but it is filtered through the foliage of the trees above. Your light should be bright enough to cast soft shadows.
Low Humidity: Ideally Above 40%
This Hoya tolerates a drier environment. However, it could still benefit from light humidity care, including misting and grouping together with other houseplants. May require humidifier in cooler, drier months.
Intermediate: Lowest 60F
This hoya does not require high heat, but does not tolerate cold as well as other varieties.
Does Sunstress
This plant has evolved to shift color when exposed to bright sunlight, much like a human getting a tan. This does not harm the plant with proper care.
