I was recently advised to grow "Willow" for cloning reason later on. Seems something in the bark or woody stems of Willow trees has an active ingredient that is used for making clones.
Yes, willow has a high concentration of rooting hormone. I think it is concentrated in the whips, particularly the tips. I think you pretty much crush some willow tips, soak in water and use that 'tea' to root whatever cuttings you are trying to make.
I own a copy of this book:
American Horticultural Society Plant Propagation: The Fully Illustrated Plant-by-Plant Manual of Practical Techniques by Alan Toogood
I have not read any of the other suggestions here so I don't know how it compares to them, but it has an exhaustive list of species and techniques for cloning, grafting, seed, etc. It seems like a good general reference for beginners, and it is a very attractive book.
