Indigo bush
Indigo bush is well suited to the dry conditions of the desert. Its small, narrow leaves help conserve moisture, reducing water loss under intense sun and heat. Like palo verde and ironwood, both members of the pea family, indigo bush responds to drought by dropping its leaves during dry periods. When this happens, its pale bark and sharp spines give the plant a dead, skeletal appearance, even though it remains alive and adapted to endure harsh conditions.
In wetter seasons, especially during a good spring, the plant changes noticeably. Fresh growth appears, and deep blue flowers brighten the desert landscape. These blossoms provide nectar for migrating butterflies, making indigo bush an important seasonal resource for desert wildlife.
Through these changes, indigo bush shows the desert plant's ability to shift with the seasons. It conserves water during drought, then quickly takes advantage of rain, supporting both its own survival and the larger life of the bajada community.
