Flora and Fauna Illustrata Coloring Pages

Want to get a jump on Arbor Day activities? We’ve turned images from the Andersen Horticultural Library’s Flora & Fauna Illustrata (FFI) collection into coloring pages. Help us celebrate this wonderful collection by adding your own artistic touch. When you’re done coloring, email a photo of your creation to, and we might post it on our Nature Notes blog, Instagram or Facebook.
