Congratulations to Hossein Noorbakhsh who received a 90 point CCE/AOS for his Brassavola nodosa at the AOS Judging Center in Ann Arbor, Michigan, (with the help of Dave Miller, our OSWP AOS judge and thoughtful transport). 

The Certificate of Cultural Excellence is a rare and wonderful AOS award to the grower for cultural excellence. Hossein’s plant had so many flowers in great condition and spotless leaves.  The flowers surrounded the plant and were in top shape.  
Congratulations again to Hossein for his Brassavola nodosa and his CCE.
