Dendrobium parvulum (syn delicatulum)

I wonder if there actually are other blue clones? Sounds like perhaps the violet blue should be crossed to a different color (ie white) then backcrossed to the blue. Unless we can verify different clones and cross them

 

Thanks, Marni. That solved the mystery.

and here is the tag:

 

Same tag.

 

Marni, your plant is fantastic! I have admired this dendrobium for sometime. Thanks for all the useful information.

 

2 years of growing this stupid thing and it finally flowers.

 

This is truly a small gem of Dendrobium. Both Marnis and your plant looks great. I'm having trouble getting this to grow well. I'll study the recommendations given in this post carefully.

Dpfarr - How do you grow yours?

 

Nice job on getting it to bloom, this is a tricky one. I haven't figured out the magic formula yet to get this one to bloom regularly even multiple clones.
As far as the correct name I think the taxonomy on section oxyglosum is still being worked out.
The largest plant blooms with some regularity and it's from tom Perlite, most likely the same clone as Marni's, the one with the light green foliage is a white flowered form
and blooms some times with a nice pure white flower that does open and last.

 

Nicely grown Mike!

I'm almost entirely certain all the blue clones are genetically identical, they are all japan imports (just like subuliferum, prasinum, and a few others), and even sold under the "violet-blue" name here in Europe. Same for the white form.

My imported PNG clone which arrived as 3-4 bulbs in 2013 is starting to really take off, I suspect it will still be a few years until it flowers but perhaps i'll be surprised earlier.

@Mikael grow all oxyglossums the same, can you grow it under the same conditions as your subacaule?
