Helichrysum lamarckii

Helichrysum lamarckii is a perennial herbaceous plant belonging to the Asteraceae family. This species is widely recognized for its high ornamental value and its durability, as the flowers retain their shape and color even long after harvesting, making them a premium material for dry floral arrangements.

Originating from the Mediterranean region, this plant has evolved to thrive in arid and harsh environments. Its natural habitat is characterized by poor, rocky soils and high solar radiation. Currently, it is cultivated globally in regions that mimic its native climate, particularly in areas focusing on water-wise landscaping and specialized flower production.

Botanically, it is distinguished by its silvery, pubescent foliage that acts as a thermal regulator and moisture saver. The inflorescences are tight capitula with papery bracts that protect the inner flowers. This structural adaptation allows the plant to resist dehydration and maintain its form throughout the flowering season and beyond.

The agrotechnical requirements for this crop focus on providing excellent drainage and full sun exposure. It is highly intolerant of waterlogging, which often leads to root rot. Soils should be sandy or gravely with a slightly alkaline to neutral pH. Given its evolutionary history, the plant does not require heavy fertilization and thrives even in nutrient-poor environments.

• Full sun exposure is mandatory
• High-drainage soil requirements
• Low-frequency irrigation regime
• Excellent air circulation
• Minimal fertilizer application

In terms of usage, the plant is primarily employed in sustainable landscaping (xeriscaping) and the floriculture industry for dried products. While generally robust, the plant can be susceptible to Botrytis cinerea (grey mold) if air circulation is poor or humidity levels remain high for extended periods. Pest issues are relatively rare but may include occasional mite infestations during periods of prolonged drought.
