What a fun book. Steven Vogel has a great voice - it's like having your fun, very smart uncle sit you down and open your mind to a bunch of science that applies to plants. Everything is built up from common intuition about shapes and our everyday experience, so it's quite accessible. He also has the actual equations floating around in the footnotes for the more quantitatively minded. I learned a bunch of fun facts, but more importantly it opened my eyes to a new way of thinking about things in nature.
