Of course this is just what i remebered and saw in the garden, there were
dissertations about perennializing bulbs.

I would assume that what might survive is well known (zone ratings etc.)
but a lot depends on luck, some ground has disease in it, or is too wet
(or dry), or is somewhere mice feel safe. The same bulbs elsewhere in
the same garden will survive for many years.

Maybe worth looking at the wiki pages on 'legacy bulbs':

http://pacificbulbsociety.org/pbswiki/index.php/…

which discusses bulbs that survive a long time.
