Hoya coriacea

Hoya coriacea is a vigorous tropical vine, appreciated for the contrast between its thin, dark green foliage and its large, velvety yellow inflorescences. The name refers to an accepted botanical species, not a cultivar, and the plant is imported. In nature, the species has a broad distribution, from Thailand to Malesia. Under good growing conditions, it can become a large plant, suitable for training on a sturdy support.

Foliage and growth. The leaves are smooth, glossy, relatively thin, and less succulent than those of many other Hoya. The plant produces long shoots and has vigorous vine-like growth; as it matures, it needs space and a solid support. Its thinner foliage should not be treated like that of a highly succulent species, and the substrate should not be kept compact or waterlogged.

Flowers and fragrance. The flowers are star-shaped and pubescent, with a yellow corolla and a white corona marked purple in the center. Mature inflorescences can become much larger than those of Hoya carnosa. The flowers are fragrant; one horticultural source describes the scent as spicy, while analysis of the volatile compounds confirms a complex aromatic profile. The intensity and precise fragrance notes may vary, so they cannot be guaranteed for every flowering.

Botanical identity and origin. The accepted name is Hoya coriacea Blume, published in 1827. The commercial origin, Taiwan, of this batch should not be confused with the species’ natural distribution.

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