Yellow orchids are relatively rare. I had never seen yellow ones before. I found these in the Los Angeles County Arboretum and Botanic Garden in Altadena, California. If I had several lives to live, I would spend one of them looking for rare plants. I would not want to sell them, I would want to photograph and classify them. There are so many species, variations, and cultivars of orchids that it is a real challenge identifying them.
