Thompson Yucca (Yucca thompsoniana Trel.)
Description: Thompson’s yucca grows 6–12 feet high, treelike, with a trunk 5–8 inches in diameter. The trunk is usually unbranched. The leaves are narrow and stiff and grow in a radiating mass near the top; they are 8–24 inches long and about 1/2 inch wide in the middle. They gradually widen from the base to the middle, then narrow to a needlelike spine at the tip. The margins are horny, pale yellow, and more or less fine-toothed. The stout, 2-3 ft. flowering stalk holds a dense panicle of white flowers slightly above the foliage.
