In Harry Potter, J.K. Rowling unveils a series of plants, most of them used mainly for healing, or decoration. In the wizarding world, they eat a lot of common muggle food, using muggle ingredients. Are there any wizarding plants mainly used as ingredients in food, that are specifically magical?(Excluding all of the sweets sold at various locations)
- Gillyweed, which may or may not be used to make gillywater
- Derwent Shimpling survived eating an entire Venomous Tentacula, he even became famous for it
I only looked up plants spoken of on the One Thousand Magical Herbs and Fungi page of the wiki, no further, so there may be better examples, waiting only for someone to find them.
