A rather fast growing Hoya that reminds a bit about Hoya australis in both flowers and leaves. Entire plant is pubescent and the leaves are hard.
Blooms during from spring to fall with large, 3/4" (2cm), white and very fragrant flowers that don't produce a lot of nectar. Flowers are cupshaped and 15-20 per umbel. The scent is very strong and some find it difficult to tolerate.
Hoya calycina subsp. calycina tolerates lots of sun and prefers to be allowed to dry some between waterings. Don't let it wilt though.
Was first published as Hoya calycina without subspecies but it was automatically altered to Hoya calycina subsp. calycina when another Hoya calycina was published in 192: Hoya calycina subsp. glabrifolia.
Likes light but should not be exposed to sunlight. A protected window facing west is good.
Tolerates some drought but should not be allowed to run completely dry.
Intermediate species. Tolerates short exposure to temperatures no less than 10°C. Best grown in a regular room temperature of 20-25°C.
Flower size: 25mm
Leaf size: ca 10cm × 15cm
