Yellow Bird Japanese Magnolia is one of the rarest and the most attractive magnolias. It also has 4-inch flowers and very distinctive flower colors from the other magnolias. Yellow Bird Magnolias are hard to come by, so trying to find one is very rare. Yellow Bird Magnolias are a unique and interesting hybrid magnolia. Yellow Bird Magnolia, also known as yellow tulip tree, produces an abundance of tulip-like flowers with bright yellow petals that are perched upright at the ends of almost every stem on the tree in spring.  (USDA Zones 5-9)
