Summary
Centaurea triumfettii subsp. semidecurrens, commonly known as Squarrose Knapweed, is a perennial herb native to various habitats across Europe, including grasslands, meadows, and open woodlands. It typically grows to a height of 1-2 feet (0.3-0.6 meters) and features deeply lobed leaves and a somewhat sprawling form. The flowers, which bloom in the summer, are usually yellow or white and are arranged in thistle-like flower heads that are moderately showy. Squarrose Knapweed is particularly noted for its resilience and low maintenance requirements.
This plant is valued for its ability to thrive in poor soils and its drought tolerance, making it suitable for xeriscaping and naturalistic plantings. It is often used in wildflower meadows, borders, and as a filler in cottage gardens. Squarrose Knapweed requires full sun and performs best in sandy or loamy soils with good drainage. While it is not particularly demanding in terms of water, it does appreciate medium amounts of moisture. Gardeners should be aware that in some regions, it can become invasive and may require management to prevent unwanted spread.CC BY-SA 4.0
