Sierra seemed to remember reading something about plants inhabiting swampy areas, but what those plants were, she couldn't remember. The answer was on the tip of her tongue, though. Buttons? Some kind of buttons? Yeah, that was it, but...what was it she'd read?

When it hit her, her face sort of lit up, and she raised her hand. "I read about Blaze Again Buttons in your book, Professor," she said. "Ultimate Guide to Herbology, I mean. You wrote that they they thrive in rotting logs near swamps." She glanced down into the swamp as if she might see a million of these somewhere in there.
