There's a fascinating article on Biophilia, Nature and Decoration over at The Textile Blog. If you're not familiar with this great site, I recommend a browse through the depths of their archives on design and textiles. Mostly of a historical bent, and full of detailed images, each article comes with a selection of book titles for further research. The postings also can be listened to, although the "narrator" is computer generated and lacking the warmth of voice the articles deserve. Links to videos, e-books and contemporary artists are included as well.
