Pleated everlasting

Pleated everlasting (Latin Helichrysum plicatum) is a perennial herbaceous plant belonging to the Asteraceae family. In agriculture, it is cultivated primarily as a valuable medicinal and essential oil crop, known for its resilience and unique biochemical composition found in its inflorescences.

The native habitat of this plant includes the mountainous regions of the Caucasus, the Balkans, and Turkey. In cultivation, it thrives in environments that mimic its natural alpine origin. Its importance in the agricultural sector has been growing due to the increasing demand for high-quality botanical raw materials in the pharmaceutical and cosmetic industries.

Botanically, Helichrysum plicatum is characterized by its silvery-tomentose leaves and bright yellow flower heads. The plant possesses a robust root system, allowing it to penetrate rocky soils and extract nutrients effectively. The leaves exhibit a pleated morphology, which serves as a physiological adaptation to reduce transpiration in dry environments.

To achieve high yields, growers must ensure well-drained, sandy, or rocky soils with neutral to slightly alkaline pH levels. The crop is strictly intolerant of waterlogging, which often leads to root rot. Successful production depends on site selection, ideally on slopes with excellent drainage and full sun exposure to maximize the synthesis of active compounds.

Standard agricultural practices include weed control through mechanical cultivation and moderate irrigation during the early growth stages. Pathogens, particularly powdery mildew and various soil-borne fungi, pose the greatest threat to plant health. Proper ventilation and spacing are critical to mitigating these risks. Economically, the plant is harvested for its dry flowers, which serve as the primary source of medicinal extracts.

• High drought and frost resistance.
• Essential need for well-drained soils.
• Harvesting at the peak of full bloom.
• Rich in flavonoids and essential oils.
