Phrag self pollination?
 

I have a Phrag czerwiakanianum which recently bloomed.

Two of the blooms produced seed pods which opened around May 28, 2006 with
lots of seed. I did have other Phrags in bloom at the same time but the
possibility of an insect for pollination bigger than a fungus gnat, if that,
is remote.

Can these self pollinate?
