Update on Cuttings from Garden of Hayden: How are they doing now? – Carla's Hoya haven

I purchased a batch of 7 cuttings from Garden of Hayden in late September 2023. That was my Tenth Hoya Haul of 2023. I rooted them semi hydro in Fluval Stratum which has worked incredibly well for me. I allow the cup of dirt pellets to almost dry out between waterings which keeps my Hoya cuttings from rotting. The pellets also provide much needed nutrients and encourage root branching. Once the cuttings rooted I then transferred them to small grow pots and used a soilless mix for planting. It’s been almost 2 months since those cuttings arrived. Let’s see how they are doing.

Hoya heuschkeliana (yellow)

First up is Hoya heuschkeliana (yellow). I purchased a H. heuschkeliana (pink) cutting in April 2023 and that one is growing beautifully on a shelf in my office. I divided this new cutting in two and both are rooted with a couple new leaves. When it arrived the leaves were quite thin and dehydrated but in the grow tent they hardened.

I’ll leave it in the grow tent until spring when I’ll put it on the shelf next to the other two H. heuschkelianas. Hoya heuschkeliana is native to the Philippines and is named for Dexter Heuschkel, director of the Manila Memorial Gardens.

Hoya verticillata albomarginata (FKA acuta albomarginata)

Next is Hoya verticillata albomarginata – formerly known as Hoya acuta. I put this one in the grow tent because the leaves were quite thin. They’ve stiffened up a bit. It’s well rooted and has started growing two new vines.

With any luck I’ll get some leaves soon. Hoya verticillata is native to the Indian Subcontinent, S. China and W. & Central Malesia.

Hoya sp. UT-033

Next is Hoya sp. UT-033. This Hoya rooted quickly and the leaves are quite firm. It’s looking good and growing a new vine. It started growing a new leaf when this picture was taken.

Sadly, the leaf was brutally ripped off the vine when it became hooked on the microwave handle and I moved the entire basket of plants back to the grow tent. I had this too close to the grow light and the vine grew up into the vine which causes some damage. I moved it lower and now it’s adjusting to less light.

The only information I can find on Hoya sp. UT-033 comes from Vermont Hoyas.

Uthai Treesukhon is a Thai Hoya collector who issued many of his plants accession numbers and Hoya sp. UT-033 is one of those Hoyas. I’m assuming it is endemic to Thailand, but have no real information on it other than its accession number.

Hoya sp. UT-039

Hoya sp. UT-039 is another one from Thai Hoya collector, Uthai Treesukhon. After rooting this one I put it into my chunky soilless mix but the leaves have remained thin and this might be one that has to live in the grow tent. It’s hard to say at this point because this could be due to my erratic watering habits. It hasn’t grown any new leaves and the one vine is dying back a bit. This is winter so maybe in the spring this one will be doing better.

Hoya pusilla

I buried Hoya pusilla deep in my soilless potting mix and maybe this was a mistake. Poor Hoya pusilla has not made any effort to grow a new vine or leaves. It is rooted in the mix but that’s about it. The leaves finally stiffened this past month. Maybe I’ll start to see some new growth before winter is over.

The native range of Hoya pusilla is Peninsula Malaysia (Pahang).

Over at A Hoya Study Corner by SC Plants they state:

The epithet “pusilla” means insignificant (too small or unimportant to be worth consideration).

I think it’s a matter of perception. The big leaved Hoyas can be quite dramatic and lovely but I can only fit so many of them into my townhouse. 

Hoya Elmeri

Hoya elmeri is doing well. It rooted and has new growth points. Hoya elmeri was formerly known as Hoya mindorensis subsp. superba. and it’s leaves should sunstress red when exposed to direct sunlight. It’s native range is Borneo (Sabah) and the Philippines (Luzon).

The leaves of Hoya elmeri and firm and it does well outside the grow tent. I kept it under the GE Seeds & Greens grow light but recently moved it to a window under a BoostGro light so I can keep better track of it in a place where it’s more visible.

Hoya verticillata ‘Choomporn’

Lastly, is Hoya verticillata ‘Choomporn’. I moved this to the grow tent early on since the leaves were thin and dehydrated. This Hoya rooted well and the leaves firmed up nicely. It already grew two new leaves. I like the shape and thick waxy texture. The leaves on this one sunstress in direct sunlight. I can find very little information about this plant online.

It’s possible this plant is native to Thailand. There is a Chumphon province on the narrow Kra Isthmus of the Malay Peninsula in southern Thailand. There are a couple other variations to the spelling of the plant name: Chompom and Chomporn. Whether or not these are all variations on Chumphon I can’t say. Thai is not written in the same latin-script alphabet that English uses so translation could simply be at the discretion of the person holding holding the pen. My cutting was sold to me as ‘Choomporn’ so that is the name I will use.

These are all great additions to my collection and I look forward to seeing these grow and hopefully bloom one day.
