Named for William Griffith, who first collected the plant. William Griffith bequeathed his collection and papers to the East India Company, which was sent to England, where they are stored in the library of the herbarium at Kew Gardens. No Botanist ever, collected and described so many species, like Griffith. His collection comprised some 12,000 species! I want to thank Mary Carroll for making this information readily available to me.

It has continued to grow well and I have up-potted it into a 4 1/2 inch clear net pot and used coconut husk chips to make up the new substrate. It seems to have liked it, and has just rewarded me with a second batch of fragrant flowers with many more on the way. I should also note that this plant picked up its pace of growth after spraying it with garden sulfur as a flat mite preventative.

It started growing really well in the summer of last year (2022), and finally rewarded me with buds and flowers for the first time in last September. I grew it in a five ounce, clear, plastic cup and used primarily tree fern fiber for a substrate.

In 2020, I made a Thai order and the vendor for some reason omitted one of my requested plants and put in Hoya griffithii var. silver in its place. I was far from thrilled as having failed with this one twice before, I was not really in the mood to try it again. I rooted it anyway, as what other choice did I have. This time for some reason I made out far better than in my previous attempts and the plant at least stayed green and alive.

I had been very successful growing the regular H. griffithii for a few years, before obtaining the silver variant. I anticipated no problem with its cultivation, but I could not have been more wrong. On two different occasions, a couple of year apart, I tried my best with it and simply could not keep it alive.

There are a few different varieties of Hoya griffithii and the variant Silver has lots of silver flecks on the leaves, which I assume is where it gets name.

I have only flowered Hoya thailandica once in nine years of keep it, and had pretty much given up hope of ever flowering it again. So imagine my surprise when I found these buds forming on my trashy looking plant. Much more to come if I manage to get them to open up!

I had to put Hoya danumensis ssp. Amarii and Hoya imperialis Palawan together since they both graced me with flowers at the same time.

Here are two sub-species Hoyas that both have campanulate flowers.

I think of all the Hoyas that I have brought back from near death, Hoya danumensis ssp. Amarii came the closest to actually dying. I was down to a single leaf that sat in a small cup of coconut chips for months before finally sending up a small vine. I really had to nurse this one to get it to survive. It also blasted hundreds of buds before I could finally get it to flower again. I really like this plant so much more than the regular danumensis, which get too large and grows too rampantly to be a good houseplant. It also has a tendency towards chlorosis, which I hate in a plant.
