Helichrysum pedunculatum is an evergreen, fast-growing perennial herb that can grow up to 500 mm tall. The stem is erect, single, unbranched, white-woolly, from a woody rootstock. The leaves are broadly elliptic, the upper surface is smooth and hairless, while the lower surface has a skin of silky-woolly felted hairs. Most of the leaves arise from the root (radical), are up to 130 x 40 mm, and taper to a petiole-like base. The stem leaves are sessile.
The flowers of Helichrysum pedunculatum are white to cream, in bell-shaped, discoid heads, 7.5 x 7 mm, with reddish-brown involucral bracts. Many flower heads are arranged in a crowded, branched inflorescence at the tip of the stem that starts out very compact and rounded becoming loose and flattish as the flowers open. The flowering time is in summer (November to February). The seeds are small and brown.
