Hoya hainanensis (sp. DaNang Vietnam) - fragrant flowers

Hoya hainanensis (sp. DaNang Vietnam) retains the commercial name hainanensis in the title. DaNang is the provenance label, not a species. The foliage in this batch is elliptic-lanceolate, dark green, glossy, with sunken veins and light tessellation; the pattern is not variegation. The flowers are small, cream-pink, star-shaped, grouped in compact umbels, and described as subtly fragrant. The growth habit is vining. Hoya hainanensis and Hoya crassipetiolata are separately accepted species. Taiwan marks the import.

Foliage and growth. The leaves are opposite, thick, and dark green, with sunken veins that create a raised pattern.

Flowers and fragrance. The umbel is compact, with small, star-shaped flowers. The corolla is cream or pale pink, slightly pubescent; the corona is pink-yellow, with a darker center. Horticultural sources note that they are subtly fragrant; color and intensity may vary depending on growing conditions. Flowering depends on the plant’s maturity and growing conditions.

Identity. The title retains Hoya hainanensis (sp. DaNang Vietnam). Hoya hainanensis Merr., published in 1923, is an accepted species native to Hainan and Vietnam. Hoya crassipetiolata Aver., V.T.Pham & T.A.Le, published in 2017, is a separate accepted species, also from Vietnam, and is not a renaming.

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