Centaurea affinis, commonly known as Affine Star-Thistle, is a perennial herb native to a range of habitats across Eurasia, including meadows, grasslands, and open woodlands. It typically grows to a height of 2-3 feet (0.6-0.9 meters) with a similar spread. The plant is characterized by its deeply lobed leaves and large, thistle-like flower heads that bloom in summer. The flowers are usually purple, pink, or white and are highly attractive to pollinators. The flower heads are notably showy and can add a dramatic touch to garden settings.

Affine Star-Thistle is valued for its ornamental flowers and is often used in wildflower gardens, borders, and as cut flowers due to their long vase life. It is relatively easy to maintain, requiring minimal care once established. This plant prefers full sun to part shade and thrives in well-drained soils. While it is drought-tolerant once established, regular watering during prolonged dry periods will keep it looking its best. It is not known for having significant disease or pest issues, but it can self-seed prolifically, which may be considered undesirable in some gardens.CC BY-SA 4.0
