Valencian everlasting

The Valencian everlasting (Helichrysum valentinum) is a perennial herbaceous plant or subshrub belonging to the Asteraceae family. This species is highly valued in commercial agriculture primarily for its role as a premium dried flower, possessing a unique structure that retains its shape and golden hue long after harvesting.

The plant originates from the arid landscapes of the Iberian Peninsula, specifically the Valencia region. Its native range defines its environmental preferences; it is well-adapted to Mediterranean climates characterized by long, hot, dry summers and mild, wet winters, thriving in high-light, open-field conditions.

From a botanical perspective, the plant is characterized by its dense tomentose (hairy) foliage, which serves as a physiological adaptation to prevent water loss through transpiration. The inflorescences are composed of composite flower heads, protected by papery, bract-like structures that are drought-resistant and slow to decay.

Agronomically, the plant demands well-drained, sandy, or rocky soils. It is particularly sensitive to waterlogging, which can cause rapid root decay. Cultural management focuses on maintaining low soil moisture levels and ensuring excellent air circulation within the field.

• Light sandy soil composition.
• Low nitrogen fertilizer input.
• Wide spacing for aeration.

The primary economic use is in the floral industry for professional dry-flower arrangements. As a crop, it faces risks mainly from fungal pathogens resulting from excessive humidity and soil moisture. Pests such as aphids and spider mites can also impact yields, making early monitoring and integrated pest management critical for healthy cultivation.
