Glen Rose Yucca
Yucca necopina


Glen Rose yucca is the most common yucca found in the sandy soils of the Western Cross Timbers. It is easily distinguished by its white leaf margins bearing white curly threads, and especially its much-branched flower stalk, which may rise to 9 feet above the 2-foot-tall, usually asymmetrical rosette. Recent field observations and molecular evidence support Y. necopina as a distinct species rather than a hybrid of Y. pallida and Y. arkansana, as was previously believed. It is closely related to Y. louisianensis. Glen Rose Yucca is on the Watch List as a TOES V species, having either low population numbers or a restricted range in Texas.
