Of 7 hoyas I have, lacunosa is the only one to bloom reliably.
It often blooms lightly in February and ,once the warm humid weather of SE New York State comes, pretty much continually. The scent is like cinnamon/hyacinth, and powerful. This plant needs humidity in the air more than heavy watering. DO NOT pull off the old blooms- the new ones sprout from them.
