Erigeron lanatus is a small perennial herb growing just a few centimeters tall. The leaves are mostly basal, each roughly lance-shaped and up to 3 centimeters (1.2 inches) long. They are coated in loose, woolly fibers. The inflorescence is made up of one flower head with white or purple-tinged ray florets measuring about 1 centimeter (0.4 inches) long. The head is lined with hairy purple or purple-tipped phyllaries. Blooming occurs in July and August. The head is an achene with a pappus of bristles.[4]

Erigeron lanatus grows in high-elevation subalpine and alpine climates. It is most often found growing in limestone scree. It has been seen growing with Siberian aster (Aster sibiricus) and starwort (Stellaria americana).[2]

Hiking and mining may threaten this species in some areas.[3]
