Hoya Callistophylla Obsidian

Hoya callistophylla ‘Obsidian’ is the dark form of an already beautiful species. Where the standard callistophylla has medium-green leaves with yellow veins, the Obsidian form takes that contrast to the extreme — deep, almost black-green leaves that make the intricate venation pattern pop in an almost electric way. It’s a vigorous grower that rewards with waxy, fragrant flower clusters once mature.
