Yucca thompsoniana, the Thompson's yucca, [3] is a plant in the family Asparagaceae, native to Texas, Chihuahua and Coahuila. [4] Other names for the plant include Beaked yucca, Soyate and Palmita. [5]

Yucca thompsoniana has a trunk up to 1 m tall, branching above the ground. It flowers before there is any trunk at all, but continues to flower after the stem begins to grow. Leaves are narrow and dagger-like, a bit glaucous, up to 35 cm long and 10 mm wide. Inflorescence is a panicle about 100 cm high. Flowers are white, about 4 cm long and appear in late March through early May. [5] Fruit is a dry, egg-shaped capsule. [4] [6]

The plant was first collected in Chihuahua by John Bigelow in 1852 and was described by William Trelease in 1911. [5]
