Recently I have developed an interest in growing sulcos. I have been reading a bit about them, mostly on the Sulcopassion site. There's a lot more to it than I first expected. Particularly when it comes to the names!
A lot of the plants I've seen and read about have field numbers, eg. Sulcorebutia swobodae HS 27. I've read that if you want a plant that has a field number, that ideally this should be a clone of the 'original'. Eg for HS 27 that'd be a clone of one of the original plants/seeds collected in Bolivia by Heinz Swoboda back in 1982.
Because its pretty well impossible to import plants or cuttings into Australia, it seems that the only realistic way to get these varieties is by using seed. However I've read that this seed doesn't always 'run true' to the original. This is supposedly due to problems with accidental and/or sloppy pollination creating unexpected crosses. Other things such as sloppy labeling were also mentioned.
So I was wondering if anyone has had any experience of growing Sulco seeds sold with field numbers. Seeing as i don't have much of a choice I'm going to try the seeds anyway. In any case it'll still be interesting to grow them. But I'm curious about these concerns with Sulco seed, and if they really are much of a problem.
