Yucca necopina Shinners,[2] the Brazos River yucca or Glen Rose yucca,[3][4] is a species in the family Asparagaceae. It is a rare endemic native to a small region in north-central Texas.[5]

Description

[edit]

This plant is a perennial shrub that grows in small colonies of rosettes.[4] The plant grows to a height of 2 feet, with bloom stalks reaching a height of 7 feet.[4] Its flowers are greenish-white and bloom in Spring.[4] The species is similar to Y. pallida and Y. arkansana,[5] and at one time it was thought the species could be a hybrid of the two; later DNA evidence supports it being distinct.[6]

Distribution and habitat

[edit]

This species grows in river terraces and deep sand, and is native to Somervell, Hood, Parker, and Tarrant Counties in Texas, west of Dallas and Fort Worth.[6][5]
