After chasing the sun all summer long trying to get Hoya curtisii to bloom, it now flowers in four separate months. I don’t know what to say about this plant; it has produced flowers in September, October, November, and now December of this year. It must be that all of the summer sun gave it the energy needed, even though the plant now practically sits in the dark. No one should ever give up on flowering the H. curtisii, because it will happen for you!
