Dendrobium sulphureum belongs to section Oxyglossum. Most species in this section are amazing miniatures that produce large flowers for the tiny plant body. Many of us are captivated by them. The bad news is that it is from mountain cloud forests of New Guinea, so it requires somewhat specialized environment. Given the appropriate condition, it seems to be a rather robust plant even though they are tiny. I haven't had this for long, and this is the first blooming. The contrast of the red lip and creamy white is stunning. I got it in spring 2015 from Far East Agriculture Orchids. The photos were taken in July 18, 2016, but the flowers opened in June, and the same flowers are still open in September, and they will last for a long time.
I'm growing it with sphagnum moss in a clay pot under a cool condition (details at the bottom of this post). It is getting fairly weak light for this species (photosynthetic photon flux density, PPFD, of 120-130 μmol/m2/s, which is just a bit higher than typical Paphiopedilum level), but it seems to be doing ok so far.

Naoki, I love the moss growing at the base, it really frames the plant great. Really nicely grown! I am glad I found your blog, it is a treat to me.
ReplyDeleteYes, it does look nice, but in reality, I have to admit that it is a bit of nuisance... It spreads from one pot to next, and I occasionally need to removed them from the pots of smaller orchids.
