| Description: | Shrublet c. 450–1 000 mm tall, branches virgate, greyish-white woolly, often yellowish in dry state, leafy (in var. aromaticum with short, stiff branches, each terminating in a small cluster of heads). Leaves mostly 20–80 x 6–15 mm, diminishing upwards, lanceolate or oblanceolate, apex acute to subobtuse, mucronate, petiole often small, but distinct in all but the uppermost reduced leaves, margins flat or somewhat undulate near the base, both surfaces closely greyish-white woolly, wool sometimes thin, 3 main veins of the larger leaves often visible on one or both surfaces, sometimes secondary nerves as well. Heads homogamous, cylindric, c. 4–5 x 2 mm, many in terminal congested or spreading corymbose panicles. Involucral bracts in 4 series, graded, inner about equaling flowers, not radiating, imbricate, oblong-lanceolate, sometimes keeled, subacute to acuminate, opaque white or inner sometimes rosy. Receptacle with short fimbrils. Flowers nearly always 5. Achenes 0.75 mm, glabrous. Pappus bristles many, about equaling corolla, scabrid, bases cohering by patent cilia. (from http://keys.lucidcentral.org/keys/v3/helichrysum/key/Helichrysum/Media/Html/Helichrysum_tomentosulum_subsp._aromaticum.htm) Differs from the typical plant in its twiggy habit with short, stiff branches, each terminating in a small cluster of heads. The heads can be as tightly clustered in subsp. tomentosulum as in subsp. aromaticum, but the open, loosely branched habit of the former is diagnostic.
