Hoya diversifolia is a much loved hoya of the Philippines. It was reported to have been found in Palawan, there is even a name H diversifolia subspecies el nidicus, which refer to that one found in El Nido, Palawan. It is reported that aside from the Philippines, it is also discovered from Malaysia, Indonesia, and Thailand. There are many subspecies and even written as varieties in hoya websites, but they are probably given by traders to show physical differences, not considering the changes they show when grown in different conditions of the environment including media, pH, nutrition, temperature, sun exposure, etc. Researches to show variations in one through time is non-existent or very limited. Moreover, even the main Hoya diversifolia name has the status of "unresolved" at The Plant List.
Long time growers very well know that hoya characteristics changes in color, shapes of flowers or leaves and a lot more phenotypically. But this species is named such because of its diverse characteristics of leaves. For example, sizes of leaves vary so much that if only big leaves are shown continuously for a long time, someone might think that it is the actual leaf sizes for it. However, the word diversifolia came from diverse or variations of the foliage.
Even with the growth of the flower buds, there are normally a few stages in one umbel at a particular time. The above umbel has at least 3 stages of flower development. But there are also umbels showing the same stages of flower growth.
The early opening buds already produce an exciting phase like the photo above. The fuchsia corona color peeps through the light colored corolla making the opening very dramatic.
Nectar is also a prominent characteristics of this hoya, giving indoor growers in temperate countries some difficulty with cleanliness. Nectar is sticky and difficult to clean most specially because flower stays open for 1 week. Scent is not very sweet nor bad, just a pale discernible flavor.
I taste all the nectar of my hoya, and i just discern the sweetness, characteristics of all their nectar.
This hoya has long internodes and really grows fast, so i allowed one plant to climb the lanzones tree. Despite our very long, hot dry season, it thrives there without any watering. The leaves just turn yellow and wilted, but recovers quickly after the first heavy rains of the next season. It is also noticeable that almost all nodes are laden with umbels.
Can you see that green praying mantis at the top right portion of the photo?
I just saw it when i post this here.
