Starthistle was a plant used as an ingredient in potions. Remus Lupin kept a jar of it in his office during his tenure as Defence Against the Dark Arts professor in 1993 and 1994.
Behind the scenes
- Starthistle probably refers to Centaurea colcitrapa, common in southern England, which was once used to treat kidney disorders.
- The plant pictured appears to be millet, a plant eaten by small birds, and very different from Centaurea colcitrapa. It may be a magical variant.
