Canyon sunflower is a coarse and leafy, widely-branched
perennial shrub rising from a somewhat woody base, mostly glabrous and
growing to about 5' tall. The leaves are alternate, thin and resin-dotted
below. They are also deltoid to ovate in shape, acute- to acuminate-tipped,
3-veined from the base, entire to irregularly toothed, and up to 6"
long. The radiate flower heads are large and showy to 2" across,
solitary on the terminal stems or slender elongated peduncles in the
upper leaf axils. The outer bracts of the involucre are foliaceous and
spreading, the inner more rounded. There are 12-21 ray flowers only
very slightly toothed and yellow, and many disk flowers with glandular
tube bases, also yellow. Canyon sunflower occupies shaded canyons, moist
wooded slopes and streambanks in southern oak woodland, chaparral and
coastal sage scrub below 3000', and is common from Baja to c. California,
blooming from February to September. These pictures are from Newton
Canyon in the Santa Monica Mts.
