USDA Symbol: XYTO2
USDA Native Status: L48 (N)
Several grayish, leafy stems, growing from a woody base, with long leafless ends topped by flower heads with many narrow, pale lavender or pale violet rays surrounding a yellow central disk.
The pastel hue of the rays seems unexpectedly delicate in the plants harsh environment, even appearing vivid in the early light of day. A similar species, Big Bend Aster (X. wrightii), is found in western Texas and nearby Mexico. Desert species with a woody base (Xylorhiza means woody base) have been removed from the large and complex genus Machaeranthera, where they were placed for many decades.
