Yucca filamentosa, commonly known as Adam's needle or curlyleaf yucca, is a resilient, broadleaf evergreen perennial shrub native to the southeastern United States. Characterized by its dramatic architectural form, it features a dense basal rosette of rigid, sword-shaped leaves decorated with distinct, curly thread-like filaments along the margins. It is celebrated in landscaping for its tough-as-nails nature and its spectacular, towering spikes of bell-shaped, creamy white summer blossoms.

Foliage grows 2-3' tall and 3-5' wide.  When it is in bloom the spectacular flower spikes can reach heights of 5-8'.  This is a very long-lived perennial, often persisting for up to 50 years.

This plant thrives best in full sun, though it shows a surprising tolerance for partial shade.

It requires well-draining soil and easily suffers from root rot if left in standing water. It prefers sandy or gritty soils but adapts to heavy clay if well-drained. Once established, it is highly drought-tolerant and thrives on neglect.

This plant shares a famous, highly specialized symbiotic relationship with the Yucca Moth, Tegeticula yuccasella.
