Here are a few macro photos that I took of the blooms:

Here is the first photo that I grabbed with my phone after most of the flowers were open:

The flowers opened up over the course of three days. Here were the first that popped open. There was no detectable scent.

In the years since I first tried to grow the plant I had switched from a peat-based potting mix to a much more open substrate consisting of primarily coir chips. This mix has made a huge difference in my ability to grow these more finnicky species. Although I have only been growing Hoya narcissiflora for a few months, it has proven to be totally unproblematic growing in coconut husk chips.

I first attempted to grow Hoya narcissiflora back around 2018, or 2019 with very bad results. I could barely keep it alive, restarting it a couple of times and losing it within a year. Fast forward a few years to spring 2024, and my very good friend Julie Kennedy from the UK sent me a nicely rooted cutting as part of a Hoya exchange. Below the foliage of Hoya narcissiflora:

Hoya narcissiflora was named after the plant genus of Narcissus, which includes daffodils, because of the similarities in the shape and look of the flowers.

Hoya narcissiflora was found in a solitary location in a lowland primary forest at 100-300 meters in elevation near Sanggau, West Kalimantan. It was growing epiphytically on a tree in deep shade with humidity above 80%.

The original collector that posted photos to Facebook provided a live specimen to S. Rahayu, and M. Rodda. They published the new species in Reinwardtia in 2017.

Hoya narcissiflora was firstly seen for sale as an unidentified species at the Flora Show in Jakarta Indonesia in October of 2014. After the plant bloomed, flower photos were uploaded to Facebook where it was realized to be a new species.

I received this plant years ago from Julie Kennedy and it came with the name Hoya sp. aff. engleriana Vietnam. I’ve also heard that it also goes by small leafed Hoya lanceolata. I do love this plant whatever name it goes by and have restarted it many times over the years. Here is it current reincarnation:
