About Yucca thompsoniana Trel.
Yucca thompsoniana, commonly called Thompson's yucca, is a plant species belonging to the family Asparagaceae. It is native to Texas in the United States, as well as Chihuahua and Coahuila in Mexico. This species is also known by the additional common names Beaked yucca, Soyate, and Palmita. Yucca thompsoniana grows a trunk that can reach up to 1 meter in height, with branching occurring above ground level. It produces flowers before any trunk has developed, and continues to flower after its stem begins to grow. Its leaves are narrow, dagger-shaped, slightly glaucous, and can grow up to 35 cm long and 10 mm wide. The flowering structure is a panicle that reaches roughly 100 cm in height. The flowers themselves are white, around 4 cm long, and bloom from late March to early May. The fruit produced by this species is a dry, egg-shaped capsule. This plant was first collected in Chihuahua by John Bigelow in 1852, and was first formally described by William Trelease in 1911.
