Hoya imperialis

Hoya imperialis is a bold, large-flowered species producing some of the biggest blooms in the genus. The plant develops long, sturdy climbing stems with broad, firm green leaves that sit widely along the vine. Flowers are substantial and waxy, typically deep pink to red with a paler centre, and form impressive rounded clusters with a noticeable sweet fragrance.

The species prefers bright filtered light, warm temperatures and stable conditions. Its large leaves and strong stems grow best when given support, and a lightly drying cycle helps maintain healthy roots. Regular feeding during the warmer months encourages new vines and flower production.
