Hoya finlaysonii UT073

Hoya sp. UT-073 is a horticultural line from the Hoya finlaysonii complex, cultivated for its rigid, narrow foliage, strongly marked with dark green veins. UT-073 is an accession number assigned by Thai collector Uthai Treesukhon. Species-level identification remains tentative. Its distinctive foliage makes this line one of the selections sought after by collectors. A plant appreciated for its natural beauty.

Foliage and growth. The leaves are elongated, firm, and relatively narrow, with a contrasting network of veins and, sometimes, irregular silver splash markings. Commercial sources describe UT-073 as having smaller leaves than many forms in the finlaysonii complex. The splash can vary from one leaf to another and does not represent white or cream variegation caused by a lack of chlorophyll. The plant has a climbing habit and can be trained on a support.

Flowers and fragrance. One horticultural source describes finlaysonii-type flowers and a lightly minty fragrance with a floral note. Some sources mention cinnamon and a duration of 3–4 days, but these details have not been confirmed for the UT-073 accession. Fragrance intensity may vary between blooms and growing conditions.

Horticultural identity and taxonomy. The UT prefix stands for Uthai Treesukhon, while 073 is the accession number of the material in his collection. The form is sold either as Hoya sp. UT-073 or as Hoya sp. (finlaysonii) UT-073; one specialist nursery considers it close to Hoya finlaysonii but does not confirm its identity.

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