The red bird of paradise, Caesalpinia pulcherrima, is a fairly common ornamental plant found throughout the U.S. It is popular because of its characteristics and beautiful flowers. It requires very little maintenance and blooms year-round. It is an attractive plant for pollinators such as bees and butterflies. The seeds are poisonous if consumed. It is drought resistant and sun tolerant. Red bird can be found many places in Austin, this particular one is on campus next to Moody Hall.
