Hoya tannaensis is a nice species that has occured in cultivation for a long time under the name Hoya sp. Tanna. For me it wasn't an easy species to bring to bloom. It took quite some time to bring Hoya tannaensis to bloom, but once it did they were breath taking. Large, pink, slightly cup shaped. The scent is very soft and it produces moderate amounts of nectar.
Leaves pointed, light green, approx 60mm long and 40mm wide with a thick mid nerve.
Flowers are pink (I've heard of clones with white flowers) and last for about a week.
Hoya tannaensis is similar to Hoya leucorhoda in both flowers and general growht.
Should not be exposed to sunlight.. A shaded window facing west or east is good.
Should not be allowed to go dry. Keep slightly moist at all times.
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: 40mm × 60mm
