General:
Stout biennial herb from a taproot; stems single, erect, 0.3-1.2 m tall, white- to yellowish-woolly.
Leaves:
Basal leaves in a rosette, oblong-elliptic, tapering to a stalked base, round-toothed, woolly on both surfaces; stem leaves numerous, alternate, progressively reduced and more lanceolate upward, smooth above, woolly beneath, becoming unstalked and entire, with clasping leaf-bases not or slightly decurrent along the stem.
Flowers:
Inflorescence a bracted, spike-like, terminal cluster, at first dense later elongating and spacing-out some of the numerous, very short-stalked flowers; corollas yellow to orange-yellow, sometimes white, wheel-shaped, 2-5 cm across, 5-lobed, the lobes nearly equal, concave, the tube very short; calyces 5-12 mm long, longer than the flower stalks, hairy, deeply 5-lobed, the lobes lanceolate; stamens 5, the 3 upper filaments densely, long, white-hairy, the 2 lower filaments smooth or nearly so.
