Hoya archboldiana and Hoya ‘Kaimuki’ happened to be flowering at the same time. Hoya ‘Kaimuki’ on top and H. archboldiana on the bottom.
Here is a photo of Hoya sp. EPC-610 aff. acuta showing the entire plant:
I flowered Hoya sp. EPC-610 aff. acuta in May of 2017 and August 2018. It cannot be considered a prolific bloomer, or quick grower, but I think the results are worth the effort.
Other than having an Epiphytica accession number, I have no information on this plant.
Here are a couple of flower close-ups of Hoya sp. EPC-610 aff. acuta:
As with most Hoyas with these similar flowers, Hoya sp. EPC-610 aff. acuta has an outstanding fragrance, which I wish I could reproduce here for you.
Hoya sp. EPC-610 aff. acuta was an exceptionally slow grower, but in about a year it produced a peduncle which produced flowers within a couple of months.
I received Hoya sp. EPC-610 aff. acuta as a cutting from a fellow enthusiast from North Carolina in the Summer of 2016. It had these gorgeous succulent, very thick leaves.
Many of these Hoyas will not make it back into the house this year as they have outgrown me. I’m giving them a few more months of very good growing, before the end.
One half of my extremely ugly, but very effective outdoor tent greenhouse with shade cover. The first plant is Hoya sp. IML 0557, which will flower for the first time in 6 or 7 years!!
