Hoya undulata (round leaf)

Origin and Discovery: Hoya undulata was first described in 2015 by researchers S. Rahayu and M. Rodda. This variant, known as the Round Leaf Clone, features distinct round, cupped leaves that grow wide, setting it apart from other clones of the species. It is native to the Kalimantan region of Indonesia.

Natural Habitat: The Round Leaf Clone of Hoya undulata thrives in the tropical forests of Borneo, growing as an epiphyte on trees in the humid and shaded forest environment. Like other clones, it forms domatia in its leaves that provide a habitat for ants, similar to Hoya mitrata and Hoya darwinii.

Description:

• Leaves: The leaves of this clone are round and tend to have a more cupped shape. They grow wide and maintain the undulated (wavy) margins typical of Hoya undulata. The leaves can vary in color from olive green to deep burgundy with pink variegation depending on light exposure.
• Flowers: The flowers have a unique corona with lobes that develop two lateral hooked appendages, distinguishing it from other Bornean Hoyas.

Care Instructions:

• Light: Prefers bright, indirect light. In brighter conditions, the leaves can turn a deeper burgundy, enhancing their visual appeal.
• Watering: Allow the soil to dry out slightly between waterings to avoid root rot.
• Humidity: Thrives in high humidity environments. Regular misting or using a humidity tray can help maintain moisture levels.
• Temperature: Best kept in temperatures above 75°F (24°C). It is sensitive to cold and should be protected from sudden temperature drops.
• Soil: Requires well-draining soil to prevent overwatering issues.

Fun Fact: The domatia formed by the leaves of the Round Leaf Clone are similar to those of Hoya mitrata and Hoya darwinii, providing a unique habitat for ants and showcasing a fascinating adaptation.

Hoya undulata Round Leaf Clone is a striking and unique addition to any Hoya collection. Its distinct leaf shape and ease of care make it a standout choice for both novice and experienced Hoya enthusiasts.
