When my Hoya vine blooms with clusters of pink waxy flowers it is truly exciting! Truthfully, for the first few years after purchasing this plant, it didn't bloom at all, and I didin't even know that it had the capacity to bloom, funny enough. But after producing a bloom or two, the plant has become an even more proliferous bloomer with each succesive year, and it is such a joy to watch the tiny buds develop into these stunning flowers, especially on a plant that doesn't even seem to be known for its flowers!
It is true, my hoya lives outside in a sheltered and shady spot most of the year (except for near freezing temps when it is brought indoors) so it may be happier than many of the Hoya houseplants one sees in interior photos now that plants are all the rage. But I'm sure if given a bright spot, and well cared for, you can get your Hoya to bloom too!
I really don't know too much about my Hoya, except that it is really quite happy with regular watering, and a shower now and then to keep scale and pests at bay from its tight clusters. My next task is to find some vermiculite or course mixture of bark and to experiment with rooting sections of the vine, as I read that one can propogate with cuttings any time of year!
And truthfully I wouldn't mind having a few more pots of Hoya here and there! Of course just taking care of the mini jungle that i already have can sometimes be more than enough, so I can't say for sure when this rooting experiment will happen, but when it does I will be happy to share it with you. In the mean time I have my eye on some cuttings from a neighbors huge Pathos vine, that I know root easily! Happy container gardening!
