What Is a Joshua Tree? The Joshua tree (Yucca brevifolia) is the namesake of Joshua Tree National Park and a defining feature of the Mojave Desert. Once classified as a giant lily, modern DNA research has placed it in the Agave family.
Joshua tree (Yucca brevifolia) is a slow-growing, long-lived, and unique evergreen tree. It needs very specific desert-like conditions to thrive.
The Joshua Tree, scientifically known as Yucca brevifolia, is not only a plant of unique beauty but also an important component of its native desert ecosystem. Its resilience and distinctive appearance make it a fascinating subject for study and a cherished symbol of the American Southwest.
