About the Adams Needle :
The Adams Needle bush, Yucca filamentosa, has
stiff evergreen rosettes and are part of the scene
in hot dry Central and North American scrublands.
Yuccas are hardier than they appear, and only fail
in cold exposed inland positions, where they are
better grown as container plants. Otherwise they are
handsome architectural foliage plants for dry, sunny
This variety has a white edge. Yucca filamentosa
makes dense clumps of stiff leaves 30 inches or so
long and edged with fine curly hairs. The remarkable
flower-spikes, 6' or more high, appear when plants
are five or more years old.
