description

Yucca arkansana grows solitary, without trunk (rarely with short trunks up to 15 cm in height) or in groups. The grass-like, thin, soft, flexible, green, blue, sometimes white with fine fibers at the edges, leaves are 20 to 60 cm long and 1 to 2 cm wide. The racemous inflorescence beginning in the leaves becomes 0.6 to 2 meters high. The bell-shaped, tubular, white, cream-colored flowers are 3 to 6 cm long and wide. Yucca arkansana is a link between the east coast yuccas of the Filamentosae series and the western representatives. The flowering period is from June to July.
