Because of its long leaves and less regular head of leaves which are upright or in various angles, it is not so popular.
The leaves are rigid and 80-140 cm long and 4-5 cm wide.
The Y.torreyi has in general a yellow-green colour, but an attractive blue-green form also occurs in the Big Bend Area in west Texas.
The inflorescence starts in a beautiful purple colour and the flowers later develop a completely creamy white.
Y. torreyi occurs in northeast Mexico and the states of Texas and New Mexico and is very cold hardy, down to -15°C.
