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 borders. 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.
