Stout, erect, viscid ephemeral or short-lived perennial to 3 m tall; stems stout, sparingly branched, very leafy. Leaves large, to 50 cm long, elliptic or obovate, apically acute or acuminate, basally narrowed into a winged petiole and expanded to give the appearance of 2 foliaceous stipules, the petiole and its foliose wings decurrent on the stem.

Leaves nearly all cauline; lamina lanceolate or elliptic to ovate or oblanceolate, up to 50 cm long, progressively smaller upwards, decurrent at base, winged-subpetiolate, ± stem-clasping, acute to acuminate, glandular-pubescent; upper leaves sessile. Inflorescence a dense panicle, glandular-pubescent; pedicels 5–10 mm long, lengthening in fruit. Calyx cylindrical-campanulate, 10–20 mm long. Corolla greenish cream to pink; tube 40–50 mm long, cylindrical, widest in upper 1/3; lobes broadly triangular, c. 5 mm long, acute to acuminate. Stamens with 1 much shorter than others; filaments 25–40 mm long. Capsule ellipsoidal to ovoid, 15–25 mm long.
Leaves green or brownish, not glaucous, puberulent to ± hairy and viscid on both sides; lamina of stem leaves basally narrowed into a winged petiole and expanded to resemble 2 leafy stipules, the petiole and its foliose wings decurrent on the stem; lower leaves often in a sparse rosette, up to 50 × 26 cm (elsewhere said to reach 150 cm in length), obovate or spathulate to elliptic or ovate, occasionally lanceolate, apex obtuse to acute; upper ones solitary, with lamina (3.5)5–21.5(39.5) × (1)1.5–8(17) cm, narrowly lanceolate to ovate or elliptic, occasionally obovate, apex long-acuminate to acute, entire or sometimes undulate.
Corolla pale greenish to white, sometimes pink to red in upper half or pinkish only at the margins of the lobes, 3–8 cm long, tubular-infundibuliform to salviform; tube straight or scarcely curved, dilated in upper part, 3–9 mm wide distally, not or very slightly constricted under the limb, viscid, puberulent outside; limb 3–10(12) mm long, (8)10–25(30) mm across, lobed to subentire; lobes 3–10 × 3–10 mm, broadly triangular to ovate, acuminate to acute or obtuse-apiculate, ± spreading.
Flowers often many, erect to nodding, in broad, loose, flat, sometimes rounded at the top, several–much-branched, spreading, glandular-pubescent, paniculiform inflorescences up to 23 cm long, terminal and axillary; bracts foliaceous, clasping; bracteoles small, linear to foliaceous, often ephemeral; pedicels (2)5–17 mm long, slender, later markedly thickened distally and 10–20 mm long, ± erect in fruit.
Calyx 8–25 × 3.5–8 mm, tubular or tubular-campanulate, viscid, glandular and shortly hairy; lobes unequal to equal, 2.5–13 × 1.5–5 mm, triangular to narrowly lanceolate or subulate-acicular, acute to long-acuminate, somewhat ciliate; in fruit somewhat enlarged to 25 × 15 mm and enclosing it or not.
Stamens unequal, one somewhat shorter than the other 4, usually included, sometimes slightly exserted; filaments (1)2–3.5 cm long, attached at or near the base of the corolla dilation, shortly hairy at the base and on the decurrent ridges, sometimes to near the apex, erect; anthers 2–3 × 1–1.5 mm.
A herb. It grows 1-3 m high. The leaves are nearly all on the stem. The leaf blade is sword shaped or oval and gets smaller up the stem. They can be 50 cm long. They tend to clasp the stem. The flowers are bell shaped and white to pink.
