Dendrobium unicum seeds
 

Right... So, I'm doing my own flasking and I have fairly good success rate with my NOID phal and catt seeds and purchased dendrobium seeds, but the unicum... The one that I'd like most of all to show some signs of greenery and protocorms.... oh boy...

Are they known to be hard to propagate? Do they take longer than many other dendrobiums? Do they somehow require different conditions? Warmer, colder...brighter?


It could of course be the seeds, but before I discard them I thought I'd hear if any of you have some experience with sowing dendrobium unicum.

How long ago that you flasked them? Some seeds take upward of a year to get going.

It varies. The oldest are only about 3 months. Not that old, I know, but I've been planting four different dendrobium seeds at the same time and the three others (christyanum, lituiflorum and a home-made phal-den NOID) have all produced protocorms by now. So that's why I'm wondering if the unicum is known to be slow or fussy.

The youngest flasks are just two weeks, but both the christyanum and lituiflorum show sign of greenery already.
