Achillea setacea: Bristly Yarrow

Achillea setacea, commonly known as bristly yarrow, is a flowering plant belonging to the Asteraceae (daisy) family. The common name "yarrow" is also broadly applied to other species within the Achillea genus, notably Achillea millefolium.

Taxonomy and Nomenclature

• Scientific Name: Achillea setacea Waldst. & Kit.
• Family: Asteraceae (daisy family)
• Kingdom: Plantae (plants)

• Achillea dolopica Freyn & Sint.
• Achillea millefolium var. setacea (W.K.) W.D.J. Koch
• Achillea millefolium subsp. setacea (Waldst. et Kit.) &#268elak.
• Achillea fililoba Freyn
• Achillea kuemmerleana Prodan

Distribution and Habitat

Achillea setacea is native to South, Central, and Eastern Europe, extending eastward through Russia and Central Asia to China. It has also been introduced and cultivated in many other parts of the world.

Morphological Characteristics

• Stems typically range from 15-30 cm in height, but can reach up to 45 cm.
• Stems are erect or ascending, usually simple, and feature 12-20 internodes.
• Middle cauline leaves are narrowly lanceolate in outline, measuring approximately 3 x 0.5 cm.
• Leaves are 3-pinnatisect (divided into three pinnate parts).

Ecological Role

This species is adapted to xerophytic habitats, which are dry environments. It is a close relative of Achillea millefolium, but generally shorter in stature.

Chemical Composition and Uses

Studies have investigated the sesquiterpenelactones present in Achillea setacea, noting their antiphlogistic (anti-inflammatory) activity.

Essential oils extracted from Achillea setacea have been studied for their antimicrobial properties.
