There is a reason why this is one of the commercially propagated and sold Hoyas that can be found all over the U.S. It is very easy to grow, looks amazing, and has tons of lightly scented flowers. Can you ask for much more in a plant? I don’t think so!

I sold a lot of this plant on eBay this summer. I find that it is very easy to get a lot of little plants, but quite difficult to have a large healthy specimen. Here is a flower bloom from this week in the grow tent.

Hoya vitiensis is a strange plant that I really don’t have much understanding of at all. I have gone years without flowers and then it flowers 3 times in the same year! I can’t figure it out that is for sure.

The flowers on Hoya danumensis are absolutely outstanding and probably the nicest on any of the campanulate Hoya species. If I could only figure out why I have yellowing leaves, I would give this plant my highest recommendation. It is worth picking up though if you can find it as your growing experience might be totally different from my own.

In my warm humid grow-tent, the flowers began to close up at the end of three days and were pretty much gone after four. The flowers had no real nectar and I could detect no scent.

I have wracked my brain trying to figure out what causes this condition in some of my thin-leafed Hoya species such as Hoya phyllura. I’ve tried different fertilizers, growing medias, growing it drier, and warmer but I can’t seem to solve the puzzle. I don’t know if it could be a pH issue with the nutrients getting locked up because of the media being to alkaline or acid. All I know for sure is that it is frustrating as I hate yellowing leaves!

‘Hoya danumensis is found in lowland to hill mixed dipterocarp forest and also in hill forest on ultramafic soils at 100-600 m.’ From the book A Guide To Hoyas of Borneo by: Anthony Lamb and Michele Rodda.

My understanding is that Hoya danumensis was in the trade for a very long time where it was mistakenly being sold as Hoya wallichii. The plant was correctly published as Hoya danumensis in 2009 by M. Rodda and T. Nyhuus.

I was amazed at the size of the buds as they kept growing. They were roughly twice the size of the buds on my previous campanulate Hoya species H. campanulata. Finally after 2 years of fooling around with this plant, one morning the first flowers began to open up, and I was blown away by how large and beautiful they were.

After bringing my plant inside the house, from being in my summer greenhouse, inexplicably on one of the peduncles, the buds actually began to grow. I had it under LED lighting in my basement grow-tent in a four inch net pot inside of a cache pot. Below the entire sad looking plant:
