Hoya obscura is one of the best Hoyas to cultivate. Leaves are small to medium sized an the plant can be grown on trellis or haning baskets. It does not twine very well so it needs help around the trellis, on the other hand it's easy to keep it there as it doesn't twine so much around near by plants.

Leaves approx. 7cm long and 4cm wide (2⅔" by 1½"), sometimes smaller. Dark green in color with very visible, light green veins. The leaves may turn red in sunlight which is very decorative and the venetion makes a beautiful pattern.

Flowers are quite small, approx 0,8cm (⅓") and not very fragrant, however they can vary in color from yellow to pink or the whole scale in one and the same umble.

Can be placed in any direction and blooms anywhay. Tolerates drought but is nicer looking if not allowed to run dry all the time.
