Asteraceae herb forming a large clump with slender stems and barely 5-8 mm across yellow radiate heads, Sunnyvale, CA. Pl. help in ID
I never bothered to figure out exactly what it is, but I get a million of them in my yard every year so it's definitely a weed.
Reminds me of Dittrichia graveolens/ stinking fleabane ?
Hawkweeds, Heiracium are another possibility. Some are basal clumps, but some grow taller, and many have the squared off tips of the flowers that these pictures seem to show. Many have hairy leaves.
