Hoya sp. NS05-240 was discovered in 2005 by Nathalie Simonsson during her travels. I am unsure where this plant is endemic, and if any of you out there know the answer, please contact me. I know that I received this Hoya as a cutting from Ric Morier probably in 2013, or 2014.
I started this cutting over many times during the first 3 years that I owned this plant, and invariably I would rot the roots off. It was just a very difficult Hoya to get growing. I would just start to see some new growth, and then it would just sit there for months doing nothing. The leaves looked like those on Hoya DS-70 and I expected it to be easy like that plant and nothing could be further from the truth! After 3 or 4 years of fiddling with this Hoya, It finally turned the corner when I started it over using a series of net pots where I could actually see what I was doing as far as watering the plant. I was thrilled to finally see good growth and an actual plant materializing out of the tiny cuttings that I was forced to use this go around with this tough to grow little Hoya. After about two years of growth, I was finally rewarded with my first peduncle, and was really thrilled!
I was completely taken by surprise at how long the peduncles on this Hoya were. I think that they are among the longest in the Hoya world; below you can see that the peduncle itself is 9.5 inches long. Add in the length of the pedicels and your talking almost 11 inches! Hoya sp. NS05-240 is one of the many Hoyas in the section called Acanthostemma.
This Hoya was a real challenge for me to not only bring into flower, but to grow as well. I think if you follow my advice and grow this plant in a series of net pots, it is a plant that can be brought into flower in a couple of years when grown in a warm high humidity environment. If you don’t have such an environment, I think there are better candidates to consider such as good old DS-70. I am however very happy that I was able to flower this one on two separate occasions. I rate this Hoya on a degree of difficulty scale with 1 being dead easy and 10 being impossible at a 6.
