I am posting this as a way to gather information on how to sprout my newly acquired B. 'Goliath' x guehoi seeds. Since I do not ahve any gibberellic acid or other germination helping products, I am wondering if anyone has tried using scarification for the harder to germinate Byblis, and whether it works. I'm a newbie with this genus, so any help is appreciated. ;D
I don't have gibberellic acid either, but I have used the bleach method with good success to germinate B liniflora. About 1-2 weeks ago I tried it on the cross you mentioned (as well as B guehoi) from the ICPS seed bank and so far have no germination, unfortunately. I have not tried scarification.
I am happy to say that, while it is only one, I do have a B. 'Goliath' x guehoi sprout. Hopefully it will survive, and hopefully I can see at some point in the future if backcrosses are possible, like with B 'Goliath'.
