Dear Friends, I think there is some confusion here, so let me re state my earlier note. It is believed that ALL extant plants of this species (once known as 'Bidens)are self sterile plants All plants are the result of division or now more often tissue culture i.e micro-propagation. Thousands if not tens off thousands are sold annually. Some unknown time back a report came that the plant believed to be extinct in its native Mexico was found and seeds collected. The growth of these seeds, production of new seeds, distribution is completely unknown to me. I'd appreciate some facts on this. A few years ago a couple of gardeners in New Zealand became aware that their fertile seed producing garden plants were quite unique and made seed available to a couple British growers. Some of this is detailed here http://www.srgc.net/forum/index.php?topic=6197.60 (Thanks David). Seed produced in the UK has been distributed sparingly. Kew gardens has also been involved in growing these new seedlings. The old sterile cone has proven fertile if crossed with any of the new seedlings confirming its self sterility, but willingness to produce seed if out crossed to another individual. The few seeds I was given came from a UK source. A couple of interesting items: It would seem appropriate that the original widely grown and propagated clone should now have a cultivar name to distinguish it from new named cultivars. There is at least one new named cv 'Choca Mocha' http://bigdipperfarm.com/cgi-bin/searchstuff.pl/… Surely more named cvs will be introduced. But back to my original request.... Do any of our members have experience growing seeds of this species? Thanks Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
