Thousandleaf

Thousandleaf is a common name that can refer to several different plant species, most notably members of the Achillea genus. The most frequently associated species is Achillea millefolium, also known as common yarrow. This perennial herbaceous plant is native to temperate regions of the Northern Hemisphere, including Europe, Asia, and North America. It is characterized by its feathery, finely divided leaves, which are the origin of its common name, as they appear to be composed of numerous small leaflets. The plant typically grows to a height of one to three feet and produces flat-topped clusters of small flowers, usually white or sometimes pink or yellow, from late spring through fall.

Achillea millefolium has a long history of medicinal and culinary use. Traditionally, it has been employed in herbal remedies for a variety of ailments, including wound healing, digestive issues, and inflammatory conditions. The leaves and flowers can be used to make teas, tinctures, or poultices. In some cultures, the plant has also been used as a bittering agent in beverages or as a culinary herb. Due to its attractive flowers and hardy nature, common yarrow is also frequently cultivated in gardens as an ornamental plant and is known for its ability to attract beneficial insects. Other plants might occasionally be referred to as thousandleaf, but typically context or further description is needed to identify them.
