Thanks for the tip .Bushmans Herbaria is sold as a cutting at floweryfield in austria. Good to know ciskei by tropicalseedscompany isnt on it's own might be worth getting a cut and comparing the two or even crossing them?
Now, I just have to figure out how to get such a cutting or organise someone who does have one and will grow my seeds to do a cross.
This would be, from a genetic diversity point of view, very favourable as the Ciskei line by TSC IIRC goes back to only two couples followed by 4-5 generations of further heavy selection. The Ciskei seems like a fairly healthy plant to me and still a good way from inbreeding depression but still...
You're right, it would be really nice to compare the two even if it's just out of curiosity.
