Months of bad growing, slowly turned into years of struggle with this plant. I had tried it in every Hoya growing mix known to man, but always the same pattern of re-root and deterioration would repeat. I came close to throwing it out on numerous occasions, but was loathe to, because it was one of only a couple of plants that I had in my collection from the legendary Toril Nyhuus. Below the leaves of Hoya yuennanensis:
I wish that I could say that this little cutting did well for me out of the gate, but it grew only sporadically and not particularly well at any time. The usual pattern was that I would grow it for around 6 months and be forced to start it over. The plant was exceptionally easy to root; it would put on a few leaves and then just languish and usually need to be started over again because of root rot.
I received Hoya yuennanensis as a tiny four leaf rooted cutting in the spring of 2016. It came from an order that I made from Torill Nyhuus using Julie Kennedy as an intermediary. This was the same order that included the all white flowered Hoya Bella (PES-03).
Tomorrow I begin my discussion of Hoya yuennanensis. This has been a perennially difficult Hoya for me to grow, and up until this week a plant that has never flowered for me. The wait is over!!
I wish that I had more information on this plant, other than acquiring it from Indonesia. If anyone knows any additional info, please let me know. I believe that Hoya aff. lambii (SLM 04) is a plant best left to completist collectors as it would never make it in the regular house. I believe that it needs very warm, humid conditions in order to thrive. That being said, the flowers are quite nice to experience in person, and the plant is somewhat easier to grow that the original Hoya lambii.
Here is a photo of the entire plant. You can see that the plant does not have to be very large in order to flower. I have now flowered this plant on numerous occasions on two different peduncles. It appears to be one of those plants that is easy to bloom, but hard to grow well.
The flowers of Hoya aff. lambii (SLM 04) last exactly one day just like the regular Hoya lambii. They drip nectar, but because of their short duration, they don’t make too much of a mess. There is a light strange fragrance that is kind of indescribable.
I wondered why this plant was called Hoya aff. lambii, when the leaves looked almost nothing like Hoya lambii. The leaves were more reminiscent of some of the Hoya Finlaysonii Complex than H. lambii. I quickly found out that the flowers are virtually identical to H. lambii.
I found that this Hoya has grown exceptionally slowly and put on very few leaves. Finally in April of this year, I spotted my first peduncle starting to grow, and buds followed soon after.
I received Hoya aff. lambii (SLM 04) from an Indonesian vendor in the middle of the summer of 2022. It arrived in pretty rough shape with just a couple of useable leaves which I was fortunately able to root in coconut husk using a warm propagator box.
