Dear Friends, I am sure regular readers of this forum and of the wiki are aware of the odd history of this tuberous species. See http://pacificbulbsociety.org/pbswiki/index.php/… The plant was originally collected in Mexico, then believed to have become extinct. All cultivated plants are a single clone propagated by micro-propagation or division of its Dahlia-like tubers. The plant is sterile and produces no seed. A few years ago a fertile seed strain was 'discovered' in New Zealand and has slowly entered cultivation. Seedlings can be crossed with the established clone to produce fertile seed and at least a couple of new cultivars have been developed. By an odd coincidence I was recently given a small quantity of seed of this still very rare plant. Of course, having never grown it from seed, I'd appreciate any guidance from any of this group's members who may have grown this species from seed or some suggestions on how best to succeed. It is still too rare to mess up. Appreciate the expertise of PBS members. Thanks. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
