There is no surprise any more when these two prolific hoyas bloom but I still enjoy seeing if the size of the flowers or duration change significantly. The first, Hoya camphorifolia, is grown as a hanging plant but always seem to end up grasping onto a hook or another vine to pull itself up higher. I must confess that this is one of the plants that I can always find mingling among other closeby. The vine itself looks fragile and frail but it is very deceiving since it is a very tough plant.
The other of the two prolific hoyas blooming is Hoya sipitangensis. This one has a knack for just hanging down in the pot and rarely decides to use a new vine to go vertical. The leaves vary greatly in sizes according to their environment and they turn a blush of red in high light. The flowers are small but lend a punch of color to compete with their foliage. If you want to grow a hoya that will fill out a pot quickly and bloom early…consider growing Hoya sipitangensis.
I have been collecting and recording information daily on which hoyas are in bloom for quite some time now and would like to compare facts about when each species is in bloom. Are the same hoyas in bloom all over the world at the same time? Go to my Bloom Calendar to see which hoyas were in bloom on a specific date at SRQHoyas. Your comments may help me draw conclusions as to what triggers a hoya to bloom and what factors may contribute to when they bloom. To date I have not been able to suggest with confidence as to how to make a hoya plant bloom. Is it related to fertilizer?…light intensity?…temperature?…maturity?…humidity?…air movement?…geographic location? If you have any information, opinions, concerns or comments on anything you are learning about the ‘Bloom Times’ of hoyas…please feel free to add a comment to this blog, email me through the website or post on Facebook!
