Inflorescence of Xerochrysum bracteatum

The capitulum-type inflorescence consists of a central disc with tubular florets and a multi-row involucre made of dry, rigid bracts, which are often mistaken for petals. The density and texture of these bracts determine the quality and aesthetic appeal of the plant. The size of the inflorescence varies from 2 to 6 cm depending on the cultivar type.

Large inflorescences with a diameter of 5–6 cm are most sought after for commercial cut flower production, while smaller forms with a diameter of 2–4 cm are characteristic of compact bedding varieties. When used as dried flowers, harvesting is performed at the semi-opened stage to maintain shape and color upon drying, preventing the browning of the central part.

The quality of inflorescence formation depends directly on nutrient and irrigation conditions. Moisture deficiency and unfavorable growing factors lead to premature wilting, deformation of the capitula, or a loss of their ornamental properties.
