This one with blue pollen looks much like "Hippeastrum aulicum 'Quiririm' " from Mauro Peixoto's site. He sells seed but hasn't got that one listed, I've got a few growing nicely which I got from him. One flowered this year, H. striatum 'Petiolatum'. I have Hippeastrum aulicum 'Corupá'. I think the different names are varieties from different locations.

They are quite easy to grow if you know how.
