Description
editThis 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
editThis 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]
