A superb little alpine fleabane from the mountains of the northern Rocky Mountains, Erigeron tweedyi forms compact, low rosettes of leaves produces a succession of lavender to blue-purple daisies in summer. The plants remain wonderfully compact, typically only 4–20 cm tall. Making it perfect for the rock garden/crevice or large trough. The aff is listed because these do not seem to be as silvery/hairy as some plants I have seen before, they have been under shade cloth for a bit of our brutal summer though so that could change a bit when they get some more sun exposure.
Tweedy’s fleabane is native to Idaho, Montana and Wyoming, where it grows in exposed, dry habitats from montane valleys into the alpine zone. Its natural habitats include rocky slopes, limestone talus, shale outcrops, clay hills and sagebrush-grassland, with populations occurring from roughly 1,600 to 3,000 m.
An excellent plant for the dry rock garden, alpine trough or scree garden, E. tweedyi appreciates full sun and exceptionally sharp drainage. A lean, gritty mineral soil is ideal, and it is particularly well suited to gardens where summer drought can be tolerated. The combination of its silvery foliage, compact habit and lavender-blue flowers makes this one of the more desirable North American Erigeron for the serious rock-garden collection.
