Achillea asplenifolia

Achillea asplenifolia is a species native to central Europe, similar to the common yarrow, but distinguished by its vigour and larger size. It produces beautiful flat flower heads in shades of purple-red to pink throughout the summer, which rise above its finely cut foliage. This hardy perennial is stunning when allowed to grow freely in a wild garden. It thrives in sunny positions in any soil type, including salty, wet, and clay soils. 

Achillea asplenifolia, also known as the Fernleaf Yarrow, is often described as a variety of the more common Achillea millefolium. Its distribution area extends from southern Moravia to Austria (Lower Austria), southern Slovakia, Hungary, Romania (Transylvania), Croatia, and Serbia. It can cover wet meadows, marshes, salty environments, and ditches, often growing alongside reeds and sedges in flatlands and at higher altitudes.

This perennial yarrow forms a slightly furry shrub, reaching 60 to 80 cm (24 to 32in) in height and 60 cm (24in) in width. Its foliage is finely cut, pale green, sometimes slightly downy, occasionally glossy. The leaves of this plant look like those of a bird's nest fern and have wide terminal segments. They contain essential oils that have medicinal properties. The flowering period, remarkably long, occurs from May to September. The flat umbel flower heads are red to pink and truly vibrant.

 Yarrows are a type of plant that can thrive in sunny areas and are very hardy. Achillea asplenifolia is a particularly strong perennial that can adapt well to various conditions. It is an excellent choice for rockeries, walls, borders, or slopes, as it helps prevent erosion. It also grows well alongside brackish water or ponds. The plant spreads quickly, allowing it to cover large areas and reducing the need for mowing in low-traffic zones. It can even tolerate competition from tree roots. As it is easy to grow and highly adaptable, it is perfect for wild gardens alongside asphodels, Isatis glauca, or euphorbias.

The Achillea asplenifolia is being studied for its medicinal qualities because it contains 15 new organic compounds known as lactones in its tissues. Its essential oil might have unique therapeutic benefits.
