    Sarr cross-pollination rules?

    Hey guys,

    I'm trying to get a handle on the "rules" of Sarr pollination. I looked around and I can't find answers to these questions.

    I read that you can't self-pollinate or use genetically identical plants (dividions or TC clones), but can you cross pollinate any other Sarracenia and expect to get seed?

    Does it get very hit or miss when trying to cross pollinate using hybrids (as opposed to non-hybrids), or is this usually successful as well? E.g. I'm curious if I can cross pollinate my S. x catesbaei (pupurea x flava natural hybrid) with my Judith Hindle.

    Lastly, are there many hybrids that don't flower, or flower but will never set seed?

    Self pollinating does set seed it just doesn't always result in the seed yield you would get from a cross pollination between two more gentically diverse plants. People do it all the time though and get plenty of seed so if you want to self pollinate go ahead.

    You can breed together pretty much any two sarrs and get seed and this includes already hybridized plants so you should be more than able to get seed from the cross your looking at making.

    The only ones I know of that don't really set seed are the double flowered sarrs like leuco tarnok. I havent heard of many sterile plants apart from those although there probably are some.

    You can get some pretty interesting results when self-pollinating hybrid Sarr's. I don't know why people don't do it more often. I've read somewhere that you get inbreeding depression, but I haven't found that to be the case - maybe over several generations, but I have several first generation selfed plants and they're doing great. Cool-looking too.

    Anything goes really. Practically all Sarracenia species and hybrids are cross and self-fertile, even TC clones. In-breeding depression does occur, some species are more tolerant than others. I think it is S. flava that is one species sensitive to in-breeding depression. There have been papers published on this, try a Google or JSTOR search. I think it was Phil Sheridan's paper that I read on the subject.

    Most registered Sarracenia cultivars are clones of a specific plant so unless specified otherwise in the published description seed offspring should not be labeled as the cultivar.

    Pyro mentioned that there is a way to get seed from S. 'Tarnok'.

    How tolerant are S.purpurea to in-breeding depression?
    Some days it just isn't worth chewing thru the restraints.

    I don't know about purpurea, but I've seen some inbred plants that struggle to produce proper pitchers and grow deformed flowers.

    thats weird. so how are sundews and flytraps so effecient at self pollinating?

    Different genus, diifferent evolutionary path.
