Jim:

I can't speak to the hardiness of Sisyrinchium palmifolium, but it is 
one fine garden plant...we have grown it since 2000.  The bright yellow 
flowers are huge and unlike other species we have grown, they open in 
the late afternoon.  S. palmifolium is completely evergreen, so I'd have 
a hard time believing it to be as hardy as something like S. 
idahoense.   The other superb, but little known plant is Sisyrinchium 
'Suwanee', a plant that was wild collected in the Florida panhandle, and 
doesn't behave like any native species from that region and doesn't 
reseed around the garden.
