I just love the unreflexed corollas in this photo I took this morning of Hoya rosarioae.

I’ve never had as many flowers and buds on this plant in the ten years or so that I’ve had it. Below the buds of Hoya kanyakumariana along with what the plant looks like now on my window sill:

We end our discussion of Hoya cutis-porcelana today, but I will bring back once I have a better handle on how to grow this little beauty. I think this Hoya is one of the better new Hoya discoveries in the last few years and look forward to it becoming more widely available. It does not seem to be a difficult grower and flowers early and often. It receives my highest recommendation!

The flowers on this plant are not large, only about 5/16 of an inch in diameter, but they make a big statement. They are unusual and unlike any other Hoya flower that I have seen. They have slightly sweet scent and last about four days before partially closing and falling off.

Hoya cutis-porcelana is endemic to Samar and Biliran Islands in the Visayas, Philippines. In foliage, Hoya cutis-porcelana may look like H. camphorifolia and H. bicolensis but its flower does not resemble any known Hoya species to date. The plant was first described in 2013.

After getting that first flowering, I have flowered it a number of times since. It has also added another peduncle. I may repot this one in my conventional chunky potting mix, and take it out of the bonsai mix. I just have a feeling that I could get more growth out of this Hoya with soil.

Within 3 months after potting it up the plant developed a peduncle and began budding up. I was pretty excited as I usually am when a Hoya gets ready to flower for the first time.

Of all of the plants that came in my 2019 Thai order, Hoya cutis-porcelana was the first to put on any new growth. It grew a vine with a few leaves. I found that I only needed to water the plant very little. When I pulled the net pot out of its cache pot, I could pretty accurately determine when to water. It was only necessary every 10 days, or so.

When I received my small plant, it was growing in a very hard plug of coconut husk that was impossible to remove. I had no experience with the plant so I potted it up in a modified bonsai mix, in a four inch pot, watered it well, and put it into a grow tent. I hoped for the best.

Hoya cutis-porcelana came to me as a small plant in my early May order from AH Hoyas in Thailand. It was the first to flower out of the 13 plants that came in the box.
