Hoya nummularioides 'Yellow' - fragrant flowers, mature specimens

Hoya nummularioides 'Yellow' is the yellow-corona selection of the species from Indochina. The foliage is small, rounded to ovate, with a fine, velvety texture rather than a glossy finish. The growth habit is compact and suitable for trailing. Under good growing conditions, it produces umbels of small, white, fragrant flowers. 'Yellow' refers to the color of the corona, not to variegation or a separate taxon. Flowering depends on the plant's maturity and growing conditions.

Foliage and growth. The leaves are small, leathery, rounded to slightly ovate, matte green, and finely tomentose. The epithet evokes a coin; not all leaf blades are perfectly round. The vine is slender and branches readily; the shoots may elongate over time. The lifestyle photograph shows a compact, flowerless specimen with vines of variable length. Some leaves may have aesthetic imperfections. Vine length varies from one specimen to another.

Flowers and fragrance. The flowers are small and star-shaped, grouped in umbels. The corolla is white. In this form, the corona is yellow, rather than pinkish-red as in the typical form of the species. In cultivation, an umbel is reported to bear 10-30 flowers and lasts for around a week. The fragrance is sweet and strong; perception may vary. Flowering depends on the plant's maturity and growing conditions.

Identity. The accepted botanical name is Hoya nummularioides Costantin, published in 1912. The species is native to Cambodia, Laos, Thailand, and Vietnam, where it grows as a climbing epiphyte or lithophyte in a humid tropical biome. 'Yellow' is the label for the form with a yellow corona.

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