I will be the first to admit that most of my magic of flowering Hoyas takes place in warm, humid, and artificially lit grow tents. I am frequently asked about what might flower with no artificial aids just grown in the regular house on a windowsill. Well, the answer might surprise you; I believe that most Hoyas given enough time will reward you with flowers in the regular house, especially with the lengthening days of spring into summer. An example of this phenomena is Hoya alagensis flowering on the windowsill below. I have now seen for myself a number of Hoyas that I thought could only grow and flower in the grow tent flowering away on windowsills in the house. So if you don’t have a grow tent, don’t despair, your flowers will come, and maybe faster than you think!
