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. ......
