Because of lack of space, I move a lot of Hoyas in and out of my life, but Hoya isabelchanae is such a winner, I will be keeping this one in my collection for a long time to come. It is a plant that stays at a manageable size, blooms early and heavily, and is just a delight to have around. It is an Acanthostemma type Hoya that has no scent, but makes up for its lack of fragrance in so many ways that it is a must have! Below Hoya isabelchanae in its entirety:
At around 4 months of age, I transplanted the plant in its 3 inch net pot into a 4 inch square plastic pot so as not to disturb the roots as set the Hoya back. It grew in my regular peat-based chunky mix and budded up and flowered for the first time at around 9 months old.
After about 3 weeks in the warm humid propagation box, my small plant started to show some good root growth. You have to essentially re-root these Thai plants as they are ripped out of their media, and all of the roots are completely dried out when the plant is received. The plant grew steadily in my downstairs grow-tent and developed a peduncle at about 9 months of age.
I received Hoya isabelchanae, then named Hoya sp. GPS 7-35, in May of 2018 as small bare rooted plant. I carefully transplanted it into a 3 inch net pot and put it into one of my homemade propagation boxes. Below the buds of the plant:
I had been wanting this Hoya for some time after I first heard about it back in 2016. Little did I know that I had purchased it in 2018 under a collection number of GPS 7-35. I found this out when I researched the accession number. From the description by Michele Rodda and Nathalie Simonsson:
Distribution and ecology.
“Hoya isabelchanae is only known from the base of Gunung Boliohutu, Sulawesi, where it was collected as a sterile cutting in 2002 and brought into cultivation at the Royal Botanic GardenEdinburgh where it regularly blooms in a heated greenhouse from May to October. The species was collected in primary forest and it was growing in shaded but exposed area on a decaying tree 12 m tall. A further collection is widely available in cultivation under Gerard Paul Shirley number GPS10161 and 7-35 http://www.paulshirleysucculents.nl/shop_hoyas.htm [accessed on 24 June 2016]. This accession is apparently also from Sulawesi but no further collection information is available.”
