Erigeron tweedyi
Tweedy's fleabane is a low, silvery-leaved perennial daisy from the Rocky Mountains, grown mainly in rock and alpine gardens. The key to success is sharp drainage and a dry, open, sunny spot.
Erigeron tweedyi, or Tweedy's fleabane, is a perennial herb in the family Asteraceae. It is native to the Rocky Mountains in Montana, Idaho and Wyoming.
Tweedy's fleabane is cultivated in rock and alpine gardens. In keeping with its preferences in the wild, it does best on dry open to partially shaded sites.
Erigeron tweedyi is endemic to southwest Montana, southern Idaho, and northwest Wyoming. It grows on clay hills, rocky slopes, limestone talus, shale outcrops, and in sagebrush-grasslands, from valleys to subalpine, at 1600–3000 m elevation.
