Navajo Fleabane

Erigeron concinnus has been treated within E. pumilus; G. L. Nesom (1983b) found that these species approach each other closely in geographic range without intergradation.

Perennials, 4–25(–50) cm; taprooted, caudices simple or branched, branches sometimes rhizomelike. Stems ascending to erect, sparsely to densely hispido-pilose to glabrate, minutely glandular. Leaves mostly basal (usually persistent) or basal and cauline (petioles prominently ciliate, hairs spreading, thick-based); blades narrowly oblanceolate to linear-oblong, 10–50(–80) × 1–4 mm, margins entire, usually ciliate, faces usually hirsute to hirsuto-villous, sometimes substrigose to glabrate, eglandular; cauline unreduced or gradually reduced distally. Heads 1–5. Involucres 4–7 × 7–12(–15) mm. Phyllaries in 2–4 series (midvein region orange or yellowish), hirsute to hirsuto-villous, ± minutely glandular. Ray florets 50–100(–125); corollas white to pink or blue, 6–15 mm, laminae reflexing. Disc corollas 3–5 mm (throats indurate and inflated, hirsuto-strigose, hairs biseriate, sharply pointed). Cypselae 1.2–1.8 mm, 2-nerved, faces sparsely strigoso-hirsute; pappi: outer of scales (0.2–0.5 mm), inner of (7–)10–14(–15) bristles.

Erigeron concinnus, the Navajo fleabane, tidy fleabane or hairy daisy, is a perennial flowering plant in the family Asteraceae.

Erigeron concinnus is native to the dry mountains of the Mojave Desert around Death Valley in southeast California, north and east to Nevada, Idaho, Utah, Wyoming, Montana, Colorado, Arizona, and New Mexico; in the California portion of its range, it grows at elevations of 1200–1800 m. Some of the known populations lie inside Mojave National Preserve.

Erigeron concinnus grows in sandy to rocky soils, and can reach a height of 6–16 cm (2.5–6.5 in). The leaves are 2–6 cm (1–2.5 in) long, lanceolate to linear, broadest near the rounded apex. The flower heads are sometimes produced one per branch, sometimes in groups of up to 6, each head 7–11 mm (0.28–0.43 in) in diameter, with 50-125 white, pink, or blue ray florets and yellow disk florets.
