The blue palm lily ( Yucca baccata ) (common names in other languages: Banana Yucca, Datil Yucca) is a species of palm lily ( Yucca ) in the asparagus family (Asparagaceae).
description
The solitary blue palm lily is stemless or rarely forms a short stem, but sometimes it forms clumps. The variable blue to green leaves are 0.3 to 0.7 meters long and form fibers on the leaf edges.
The short, upright or sideways inclined, branched, dense inflorescence that begins between the leaves is 0.5 to 0.8 meters high and barely protrudes beyond the leaves. The pendulous, elongated, flowers are 4 to 10 inches long and 1 to 3 inches wide. The six bracts are predominantly white to cream in color. The outer bracts are partly reddish to purple in color. The flowering period extends from April to July.
Due to the huge distribution area, the plants are very variable.
The species is frost hardy to minus 20 ° C when dry . Old specimens can be admired in Albuquerque and Santa Fé ( New Mexico ), Twin Falls ( Idaho ) and Denver ( Colorado ). In Mannheim , several 20 to 30 year old specimens grow unprotected outdoors.
