I obtained Star of Africa last year from the CT Iris Society at Elizabeth Park in Hartford.  It has done really welll in my garden.   My eclectic collection includes about 40 hybrids of mostly Tall Bearded Irises and some SDBs.
 
I am not an iris pro or a photographer but I wanted to contribute to the discussion group in a small way.  Thanks to the CT Iris Society.  I saw the beds at Elizabeth Park yesterday again and I am grateful for all their hard work.
