Luang prabang is still available but buy several packs at least if you want to work with more than a few plants. Germination on these is at about 15% and about a third of these never grow past cotyledons.
Out of 40 seeds recently started i have 2 healthy seedlings, and 5 hopeful helmet heads and other slow growers.
Thanks for the HU I Wood. I kinda expected bad results, but it sounds worse than I expected. Probably still give it a try though.
