Agavaceae

Louisiana yucca is the species that most commonly occurs east of the Blackland Prairies in Northeast Texas, usually in dry sandy uplands. It is most common in Louisiana and ranges somewhat into Arkansas and Oklahoma. It is readily distinguished from similar yuccas by its pubescent (downy) flower stalk. Its limp, dull green leaves usually bear whitish threads along the margins. Y. louisianensis is closely related to Y. necopina.
