Native to northern Mexico, this tough evergreen has been adopted into Southwestern landscapes as a large shrub or small patio tree with an exceptionally long flowering season. From spring through fall, Mexican Bird of Paradise is covered in flushes of lemon-yellow flower spikes that are a favorite source of nectar for hummingbirds and butterflies. In milder winters, the brilliant green leaves will cling to the thornless branches, lending a tropical ambiance and ensuring year-round interest in your garden. Deadhead spent flowers and seed pods to encourage blooming.
