Hoya krohniana ‘Black’ is a striking and highly sought-after variety distinguished by its small, oval leaves that deepen from rich green to dramatic dark purple—almost black—under strong light. The compact, neatly arranged foliage gives this plant a refined, sculptural look, while its clusters of sweetly fragrant blooms add extra charm when it flowers. A rare and rewarding species, it thrives in bright, indirect light and makes an exceptional choice for collectors.
