Helichrysum setosum is a perennial from the Asteraceae family, native to South Africa, where it grows in rocky areas, grassy slopes, and open scrublands of the Cape and adjacent regions, at varying altitudes.
It forms an upright clump 30 to 60 cm tall, with well-branched stems bearing linear to lanceolate, dark green leaves, slightly bristly, reminiscent of the name setosum, from the Latin seta, bristle or stiff hair. The dark, narrow foliage contrasts effectively with the intensity of the flowers.
The flower heads are a bright orange-yellow, almost golden, large and well-rounded, with tightly packed, radiant papery bracts typical of everlasting flowers. Carried on upright stems in loose clusters, they have the unique quality of Helichrysum to retain their brilliance long after cutting and drying. Their warm, clear color visibly attracts butterflies, as frequently observed in the field. In its natural habitat, flowering extends from spring to the southern summer. In cultivation under our latitudes, it occurs from June to August.
It requires full sun and well-drained soil, poor to moderately fertile, and tolerates summer drought well once established. Its hardiness is limited to mild winters, around -5 to -8°C in dry conditions. It is suitable for sunny rock gardens, gravel gardens, and Mediterranean compositions, and is also suitable for dried cut flowers.
