    The tall bearded iris Holy Night originated from the hybridizer, K. Mohr (Mohr Gardens) and was registered in 1983. Its color is described as a deep violet purple with a deep purple beard. No picture I have ever taken can show or do justice to its true velvety beauty. It stands out in the garden as if made from an expensive velvet fabric; and its color is enhanced by full sunlight as well as shade. What is most important is the hardiness and reliability of its growth and bloom habits.
