Latin Binomial: Cnicus benedictus Common Names: Blessed thistle, Holy thistle, St. Benedict’s thistle Family: Asteraceae (Daisy family) 🌿 Botanical Description Blessed thistle is a bristly, annual plant growing 1–2 feet tall with spiny, hairy leaves and bright yellow flowers surrounded by thorny bracts. Its thistle-like appearance makes it easy to recognize, though it should not be confused with milk thistle ( Silybum marianum ), which is often mistakenly substituted. 🌍 Habitat & Cultivation Native to the Mediterranean region , blessed thistle grows best in dry, sunny climates and well-drained soil . It has been cultivated since medieval times in monastery gardens and apothecaries. It thrives in temperate climates and reseeds readily.
