Hoya hypoplasia

Hoya hypolasia is an epiphytic species from Papua New Guinea, noted for its long, pubescent foliage and branched growth. The product has circulated under the spelling “Hoya hypoplasia,” but the accepted botanical name contains the letter “o”: Hoya hypolasia Schltr. Mature leaves become firm and dark green, while new growth is thinner and lighter in color. The plant develops best when trained on a stable support.

Foliage and growth. The leaves are elongated, approximately 12–18 cm long and 4–4.5 cm wide, with a sunken midrib. Fine hairs on the surface may give the foliage a grayish-green hue. Young leaves are thinner and more sensitive, while mature leaves become firm and dark green. The plant produces vigorous, branched stems with a climbing habit.

Flowers and fragrance. The flowers are slightly cupped, with a yellowish-green corolla and a yellow corona. Horticultural sources describe approximately 15–25 flowers in an umbel, each about 2 cm in diameter, with little nectar and a duration of approximately 5 days. The current label indicates fragrant flowers, but a detailed horticultural source reports scentless flowers. Any very faint scent, if perceived, may vary between specimens and growing conditions.

Botanical identity and origin. The accepted botanical name is Hoya hypolasia Schltr., published in 1913. Accounts of the original collection place the plant growing on trees in a hilly forest near a river, at approximately 400 m elevation.

Substrate: use an airy, well-draining mix suitable for epiphytic species. We recommend the professional substrate for Hoya and Anthurium - SG Mix.
