The boojum tree (Fouquieria columnaris) is a unique plant native to the deserts of northwestern Mexico, particularly in the region of the Sonoran Desert. It is known for its tall, slender trunk that can reach heights of up to 30 feet and its distinctive, bottle-shaped base. The tree is a member of the Fouquieriaceae family and is closely related to the ocotillo. Boojum trees are adapted to arid environments, with a thick, waxy coating on their leaves to reduce water loss. They produce small, white flowers that bloom in the spring, attracting various pollinators. The boojum tree is an important part of its ecosystem, providing habitat and food for local wildlife.
