Hoya hellwigiana – tropical species with glossy leaves and fragrant pink-red flowers

🌿 General description

Hoya hellwigiana is a tropical species native to Papua New Guinea, first described in 1883 by K. Schumann. It’s admired for its elongated, glossy green leaves and its showy, waxy flowers ranging from soft pink to deep rose-red. The corolla is velvety, while the corona is creamy-white with reddish tips, giving each umbel a delicate, glowing look. Flowers measure around 2–2.5 cm and form spherical clusters of 15–25 blooms, releasing a strong, sweet fragrance, especially at night.

This species grows vigorously under bright conditions and high humidity. Mature leaves can reach up to 12 cm, and the plant tends to rebloom from old peduncles once established. It’s part of the classic tropical Hoya group, closely related to Hoya deykei and Hoya rubida.
