Hoya sp. UT-029

Hoya sp. UT-029 is a collector Hoya sold under a horticultural code rather than a confirmed species name. It is sought after for its firm, green foliage and large australis-type umbels, with creamy-white, star-shaped flowers and a burgundy mark near the corona. In some collections, it is also circulated as Hoya australis 'Halmahera', but this identification has not been botanically published. The vines can be trained onto a support. The flowers are fragrant.

Horticultural identity. The abbreviation “sp.” indicates that the plant belongs to the genus Hoya, but has not been reliably identified to species level. UT-029 is a collection code, not a scientific name. The UT-029 code remains the sales reference.

Foliage and growth. The foliage is firm, green, and leathery in appearance. Young leaves may have a reddish tint, while the veins may become redder in bright light. Some sources describe the leaves as slightly velvety. Shape, size, and texture may vary between batches because the botanical identity has not been established. The growth habit is vining, making it suitable for training onto a support or for trailing growth.

Flowers and fragrance. On plants sold under the UT-029 label, the flowers are star-shaped, creamy white, finely pubescent, and grouped in dense umbels. A burgundy or red mark appears near the corona, while the corona is cream-colored. The appearance is reminiscent of the Hoya australis group, but does not justify a definitive identification. The flowers are fragrant; perceived intensity varies. Flowering depends on the plant’s maturity and growing conditions.

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