Greetings Dr. Waddick, As the link you posted is unavailable, just for fun, I will hazard a guess without seeing the photo. Kliber is the purest yellow Hippeastrum I have ever seen. However, despite several years of searching, this elusive hybrid has proved impossible to find. I am hopeful that, through the flower show in Germany, you may have found a source for this beauty. Regards, Blanca
