These plants were...unique.

Professor Bentley had definately succeeded her mission to suprise them with things they had never seen before. August looked at his Head of House's face and then back to the odd plant. What else was unique about them?

After trying to remember what all he had seen about them in his Herbology textbook, it came to him. "Professor, isn't another quality of the plant that they can also take on the properties of other plants rather than just the people who come into contact with?" he had at least skimmed something related to that.
