S. bulbocastanum is a wild relative of the domesticated potato and is native to southern Mexico and Guatemala.  Plants are small and produce very small, white tubers on long stolons.  While they are edible in small quantities, this species doesn’t generally yield enough to grow for that purpose.  Instead, S. bulbocastanum is used in breeding programs to introduce wild traits to domesticated potatoes, particularly resistance to late blight.  Our wild potatoes are not fully isolated, so while most of the seeds will be purely S. bulbocastanum, some may be crossed with other wild or domesticated potatoes.  Any that are crossed may well turn out to be the most interesting of the batch.  S. bulbocastanum has an endosperm balance number of 1, so will generally need to be bridged through several crosses from wild to diploid to tetraploid potatoes.

25 seeds collected from mixed varieties or 3 tubers.  The tubers may be of more than one variety or all the same.
