Snargaluff tree

The Snargaluff tree is a rather vicious plant which looks like a gnarled stump until it is disturbed, at which its spiky branches attack. Inside the snargaluff are a number of small pods which, when stabbed, emit wriggling tubers. The correct way to juice the tubers is found in the book Flesh-Eating Trees of the World (HBP14).

• One of these plants grows in the garden by the Lovegoods' house (DH20).
• Sprout used Snargaluff pods to fight the Death Eaters during the Battle of Hogwarts (DH30).

The tree's inclusion in Flesh Eating Trees of the World (HBP14) strongly suggests that its dangerous attributes are not only for defense.
