Description

This plant is a perennial shrub that grows in small colonies of rosettes.[3] The plant grows to a height of 2 feet, with bloom stalks reaching a height of 7 feet.[3] Its flowers are greenish-white and bloom in Spring.[3] The species is similar to Y. pallida and Y. arkansana,[4] and at one time it was thought the species could be a hybrid of the two; later DNA evidence supports it being distinct.[5]

Distribution and habitat

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.[5][4]
