Hoya sp. 'ut 030' (Halmahera Island, Indonesia) - developed specimens

Hoya sp. UT 030 is a collector’s Hoya sold under a horticultural number rather than a confirmed species name. The title associates the material with Halmahera Island, Indonesia; this remains a commercial origin label, not a botanical determination. Product photos show elliptical, glossy, dark green foliage without splash, and densely pubescent, creamy-yellow, star-shaped umbels with a cream corona and brown center. The flowers are described as fragrant. UT 030 is not UT-029 and is not treated as a published species.

Foliage and growth. The foliage in this batch is elliptical or ovate, firm, glossy, dark green, without splash or variegation. The midrib is visible; the rest of the venation is subtle. The plant has a vining habit. The photos show young specimens trained on a stake, in a plastic pot placed inside a ceramic planter. The decorative planter is not included in the price. Leaf size and number vary from one specimen to another.

Flowers and fragrance. In plants sold under the UT 030 label, this batch produces star-shaped, creamy-yellow umbels with densely pubescent corollas and a cream corona that is darker at the center. The appearance is reminiscent of the Hoya australis group, but does not justify an identification. The flowers are fragrant; the olfactory profile has not been botanically documented for this accession. Flowering depends on the plant’s maturity and growing conditions.

Identity. The abbreviation “sp.” indicates that the plant belongs to the genus Hoya, but has not been reliably identified to species level. UT 030 is a collection number, not a scientific name or a cultivar. The claim that it is a recently discovered species from Halmahera could not be confirmed. Halmahera remains a commercial provenance label.

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