Hornbeam

Hornbeam is the head of the Department of Sufficiently Advanced Technology and, with the Sunflower Official, co-founder of the Organisation. He is a sentient Ironwood tree who was one of the Firstborn Flowers. As a Tree, he is also one of the longest living. According to the PPC Manual (specifically, this section), he is often absent from the actual Department, as he has a tendency to go on long walks in thought and become lost.
