Xylorhiza tortifolia

Xylorhiza tortifolia (Torr. & A. Gray) Greene

Mojave woodyaster, Mojave aster, Desert aster

Asteraceae (Aster Family)

Synonym(s):

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.
