| Perennials, 5–35 cm; rhizomatous, fibrous-rooted, caudices sometimes branched. |
Annuals or rarely short-lived perennials, 12–50(–80) cm; taprooted or rarely fibrous-rooted. |
erect, sparsely and loosely strigose to strigoso-villous, eglandular. |
(single or multiple from bases) usually basally ascending, strigose to villous, often slightly and minutely stipitate-glandular near to heads. |
basal and proximal cauline much reduced or present as scales; cauline blades linear to linear-oblong or oblong-lanceolate, 10–30 × 1–5 mm, largest at midstem, then relatively even-sized to peduncles, margins entire, sometimes prominently ciliate, faces glabrous or sparsely villous. |
basal (usually not persistent) and cauline; blades narrowly lanceolate to oblanceolate, basal (5–)20–50 × 3–9 mm, cauline gradually reduced distally, margins entire or proximal shallowly crenate to serrate with 1–3 pairs of teeth, faces sparsely strigose, eglandular. |
4–6 × 6–12 mm. |
2.5–4 × (3–)5–9 mm. |
20–50; corollas white, less commonly pinkish, or aging pinkish, 4–8 mm, laminae not coiling or reflexing. |
60–110; corollas white, 2.5–5(–7) mm, laminae not reflexing or coiling. |
3–4.6 mm. |
1.2–2 mm (throats slightly indurate and inflated). |
in 2–3 series, loosely and sparsely strigose, eglandular. |
in 2–3 series (margins scarious at least in inner), sparsely hirsute, minutely glandular. |

Variety villicaulis, from Anticosti Island (Quebec) and Newfoundland, has been distinguished on the basis of its relatively shorter stature (mostly 3–15 cm) and greater ratio of peduncle to leafy-stem lengths (stems and peduncles as long as or longer than the leafy parts of stems); the distinction appears to be arbitrary.

In Arizona, Erigeron versicolor grows in meadows, along creeks, and in pine-aspen-spruce areas. Erigeron versicolor is distinguished by its annual duration, nodding buds, conic receptacles, broad phyllaries, and pappi of only minute crowns. The species appears to be disjunctly divided among three regions in the United States and Mexico (D. C. D. De Jong and G. L. Nesom 1996), and habitats vary widely. This is an unusual distribution. There is much variation in duration, root type, orientation of stem pubescence, elaboration of the pappus crown, and achene vestiture, and this morphologic variation does not appear to be strongly correlated with geography.
