Hoya ‘Black Margin’ – Rare Trailing Tropical Houseplant

The Hoya 'Black Margin', a striking cultivar of Hoya carnosa, is known for its thick, waxy green leaves outlined with a dark, almost black edge — a natural contrast that sets it apart from other hoyas.

Its elegant structure and minimal care needs make it a favorite for hanging baskets, trellises, and plant shelves alike.

How to Care for Your Hoya 'Black Margin'

This plant thrives in a spot with bright, indirect light and appreciates a few hours of gentle morning sun if available. Use a well-draining, airy potting mix — such as a combination of orchid bark, perlite, and indoor soil — to prevent root rot and encourage strong growth. Water only when the soil is completely dry, as Hoyas prefer a drier environment and are especially sensitive to overwatering.

While not demanding in terms of humidity, this Hoya will reward you with faster growth and a higher chance of flowering in rooms with moderate to high humidity levels. With time and the right conditions, it can produce beautiful, fragrant blooms that emerge in small clusters from established vines.

To encourage blooming, keep the plant slightly root-bound and avoid removing spent peduncles, as new flowers will grow from the same spot in the future.
