The office was simple and quiet. She didn't need over amounts of things. She didn't like things out of order either. There weren't papers strewn about or books out of order. She had all of her books set into the bookshelves that had been left for her as basic office furniture. What space wasn't taken up by the alphabetically ordered books on natural properties of muggle plants and medicinal potions of magical plants was taken by framed pictures of leaves or buds, pressed and labeled in latin to describe the pieces and useful parts of each plant.
Those small pictures set in the bookcase were in larger supply on the stone walls. She didn't like the dark, dreariness the stone gave, so she tried her best to liven up the area with images of rare plants. She had watercolor painted diagrams of those. She had hoped to one day fill the frames with the real items.
The main draw to the room was the widened window. She had requested a window box for her plants and a wider window for it. She had a couple of odd looking plants, including an ivy type that seemed to be crawling at such a rate of speed that a human eye could watch it grow. It was hanging from the ceiling by mid-day, and had to be trimmed each night. There was a venus fly trap type plant as well that made snapping movements at the wind as it went by, trying to catch it's next meal. The last of the three plants in the box was a flowering plant that looked rather harmless, and seemed beautiful with darker tips of the petals than the inside of the flower - but the tips held a type of serum that would cause convulsions if not handled property or trimmed the correct way.
But she sat happily and quietly in the bit of sunlight the window allowed on her large desk. She even kept a potted plant on her desk - a seeming fledgling of the snapping plant in the window. Even her quill was that leaf green color, and under her robes she normally wore some color of green.
As much as she could, she wasn't sitting in that office. She was out in the greenhouse. She hated that the office wasn't attached to it - but she was required to be in the dark hole, as she thought of it, a few hours each week for the students. They should have known where she was otherwise, but it was part of the job description to have an 'open door' for questions. Why couldn't that be the greenhouse door?
