Yucca carnerosana

Yucca carnerosana is a large imposing plant, often mistaken for Yucca faxoniana which mainly grows in Texas.
Y.carnerosana can reach up to 4-8 m and usually has a single trunk which, when trimmed has a average diameter of 20-30 cm.
The trunk is dark brown with irregular furrows.
Sometimes the plant branches after flowering (when about 1-2 m high), developing mostly only two heads growing close together. Branched trunks are rare.
The green leaves are 40-70 cm long and 5 cm in width, but in cultivation they can reach a length of 100 cm forming a symmetrical head.
The leaf margin shows a brown line from which thick, curling white filaments are growing.
The panicle is 100-120 cm long, and usually towering above the leaves.
The flower stalk is 5-8 cm thick and the green-white flowers are 5-8 cm long.

Y.carnerosana is found in two regions, that are wide apart from each other. The northern region extends from western Texas into the Mexican states Chihuahua and Coahuile. The southern region is found in the Mexican states of Nuevo Leon, San Luis Potosi and Zacatecas.

Y. Carnerosana is cold hardy from -12 till -15° C when kept dry.
In cool wet winter climates it is better to protect the crown against rain, because it is sensitive to rotting.
