Growing Hoya sp. UT-163 has not been easy for me.  I have had to start it over a couple of times.  It seems to need very little water.  I have to say that it is doing better for me right now than it has for some time.  I usually make a video of a plant after I flower it, but this one is so small that it will have to wait until I get a larger plant. Below the leaves of the plant:

Uthai Treesukhon is a Thai Hoya collector that has amassed an outstanding collection of Hoyas.  I wish I knew more about him and how he came to find so many incredible Hoyas.  Hoya sp. UT-163 is one of his.

I think I received a cutting of this one in trade from a grower in NC, that I have lost touch with.  It flowered almost immediately, but has not been a good grower for me.

Hoya griffithii is usually without fail an October bloomer, but last year I decided to start the plant over as it was really looking kind of ratty.  Look what I get about seven months later from starting the cutting – flowers with many more on the way.  Hoya griffithii is a plant that is capable of flowering very early!  Also, I should repeat for those always asking me for the most powerful scents in the Hoya world – Hoya griffithii is one of those.

The flowers get even more beautiful on Hoya sp. VN Vietnam when they lose their reflex, and the corollas swing back.  The flowers held this position for about three days before beginning to fall off.  The total flowering event lasted 7 or 8 days.

Final day with Hoya erythrostemma aff. sp. Sumatra NS07-004; if it ever seriously wants to grow, I will bring it back.  This Hoya reminds me a little bit of Hoya mindorensis, which is extremely difficult for me to grow because of its high heat and humidity requirements.  I will say though that this was a Hoya that wants to flower even at an extremely young age and might be worth picking up for that reason alone.

Hoya erythrostemma aff. sp. Sumatra NS07-004 carries Nathalie Simonsson accession number.  I don’t know for sure, but an educated guess would be that she discovered this Hoya in Sumatra in 2004.

This plant was small when I received it and has only grown one full size leaf, but has a new vine, and finally new leaves are on their way.

Hoya erythrostemma aff. sp. Sumatra NS07-004 is one of the few erythrostemma that does not have hairy flowers.

Hoya erythrostemma aff. sp. Sumatra NS07-004 came as a cutting from AH Hoyas in May of 2018 and flowered in December of that year. It has barely grown, but managed a peduncle and a few flowers.
