Summary

Centaurea benedicta, commonly known as blessed thistle, is an annual herb native to Europe and extending east to Pakistan. It typically grows up to 24 inches tall and is characterized by its leathery, hairy leaves and vibrant yellow flowers that bloom in dense, spiny flowerheads during the summer months. The flowers are quite showy and attract pollinators. In its native habitat, blessed thistle is often found in dry, open fields and rocky slopes.

Blessed thistle is valued for its medicinal properties and has been used traditionally to aid digestion and liver function. It is also used ornamentally for its striking flowerheads and is sometimes grown in cottage gardens or as part of wildflower mixes. This plant prefers full sun exposure and well-drained soils, making it suitable for xeriscaping. It is drought-tolerant once established and requires minimal maintenance. However, it can become aggressive and is considered a noxious weed in parts of North America. Gardeners should be cautious about planting it outside its native range and check local regulations. It is potentially invasive outside its native range, so it is important to check local regulations before planting.CC BY-SA 4.0
