Hoya 'Black Margin' (Hoya sp.) is a rare trailing wax plant from the family Apocynaceae, native to the humid forests of Southeast Asia. It stands out for its bold dark-edged foliage and straightforward care indoors.
It produces thick, waxy leaves in deep forest green, each bordered by a bold near-black edge. The leaves have a smooth, succulent-like texture and grow along cascading vines, creating a natural choice for hanging baskets or high shelves where the stems trail downward. The contrast between the leaf centers and dark margins remains vivid year-round.
When mature and well-cared for, Hoya Black Margin produces small, star-shaped waxy clusters typical of the hoya genus, though flowering indoors depends on good light, a slight nighttime temperature drop, and allowing the plant to remain undisturbed. The blooms have a gentle fragrance. The foliage delivers high-contrast visual appeal in any light condition.
Rotate it every few weeks for even, balanced growth and keep it away from direct AC or heating vents. It is pet-friendly, so curious cats and dogs can safely share the space without risk. The plant also purifies indoor air and filters formaldehyde and other toxins. It grows well in a macrame hanger, on a high shelf, or near a bright kitchen window where ambient moisture provides a boost.

Hoya 'Black Margin' grows well in bright indirect light, positioned near an east or west-facing window away from harsh direct rays.
Water it every 10 to 14 days, allowing the top inch of soil to dry out completely between waterings.
Hoya Black Margin does best in a chunky, well-draining mix of perlite, orchid bark, and standard potting soil to prevent root rot.
It prefers temperatures between 60 and 85 degrees Fahrenheit and must be protected from frost.
