For those interested in Hesperocallis undulata-
As a follow up to the discussion, I asked Mark Dimmitt, Director of Natural
History at the Arizona-Sonora Desert Museum in Tucson whether he or anyone he
knew has attempted cultivation of this and he responded that he knows several
who have tried......"with zero success."  He states, "The bulbs never break
dormancy.  Seeds germinate, and then the yearling bulbs do the same permanent
dormancy.  No one has discovered the environmental trigger that makes them
sprout." 

Mark Dimmitt may be known to many of us as principal author of the new adenium
book (pub: Rainbow Gardens Bookshop; Tucson) as well as his Echinopsis hybrids
but his professional CV may be seen at http://www.desertmuseum.org under/ 'Staff" which
is under Reseach & Conservation.

Best,
Pamela
