The organ pipe cactus is a tall, columnar cactus native to the Sonoran Desert in the southwestern United States and Mexico. It can grow up to 20 feet tall and is known for its distinctive, upright stems that resemble organ pipes. This cactus thrives in arid environments and can live for over 150 years. In spring, the organ pipe cactus produces beautiful, white to pink flowers that bloom at night and attract pollinators like bats and moths. The plant is also an important part of its ecosystem, providing shelter and food for various desert wildlife, including birds and insects.
