Don't Throw It, Grow It: 68 windowsill plants from kitchen scraps

I have one major problem with this book. I would give it an enthusiastic five stars but for this one oversight: it's very unclear about which plants are decorative and which will actually bear fruit/vegetables. On the cover of the book it shows a recycling triangle symbol with an avocado plant, suggesting that you could run a complete cycle with avocados. I'd be astonished if anyone got an indoor avocado plant to fruit. A few plants explicitly state that you can harvest (herbs, potatoes, and a few others), while a few pretty solidly suggest that they're just decorative, but an awful lot have no mention at all. For those of us with dreams of a mini-windowsill-victory garden, that's frustrating.
Another significant problem is that they'll casually mention when a plant is poisonous (potato, in the case that i recall). No bold face, no larger font, no red warning, just an offhand mention that every part of the potato plant except the potato itself is poisonous. For those of us with pets and children in the house, a little red warning box might be nice.
Beyond those, this is a wonderful book. I have but two west-facing windows in my apartment. No dirt. No patio. Not even any windowboxes. I've found, by trial, error, and luck, a few edible/fruiting plants that i can grow with some success in my windows (hot peppers, bush tomatoes, basil, mint). This book has 68. Sixty-eight. Wow.
And that's not even including hot peppers and tomatoes, which i suppose are less decorative than some of the book's suggestions.
Another omission that i'd love to see rectified in a future version of this book is the damp-paper-towel germination method. They include instruction on starting in water, soil, and gravel, and even have a description of the sphagnum-moss bag method, but for some seeds (avocado, especially), all you need is a dark place, a damp paper towel, and a plastic container. There's no reason to muck around with a sphagnum moss bag for that.
I know that sounds like a lot of criticisms for a book i call wonderful, but trust me, it's wonderful. It could be better, but it's still wonderful. Sixty eight plants!

Magic and wonder hide in unexpected places — a leftover piece of ginger, a wrinkled potato left too long in its bag, a humdrum kitchen spice rack. In Don't Throw It, Grow It! Deborah Peterson reveals the hidden possibilities in everyday foods. Peterson, former president of the American Pit Gardening Society, shows how common kitchen staples — pits, nuts, beans, seeds, and tubers — can be coaxed into lush, vibrant houseplants that are as attractive as they are fascinating. With Peterson's help, a sweet potato turns into a blooming vine; chickpeas transform into cheery hanging baskets; the humble beet becomes a dramatic centerpiece; and gingerroot grows into a 3-foot, bamboo-like stalk. In some cases the transformation can happen overnight! Don't Throw It, Grow It! offers growing instructions for over 50 plants in four broad categories — kitchen vegetables; fruits and nuts; herbs and spices; and more exotic plants from ethnic markets. The book is enhanced with beautiful illustrations, and its at-a-glance format makes it a quick and easy reference. Best of all, every featured plant can be grown in a kitchen, making this handy guide a must-have for avid gardeners and apartment-dwellers alike. Don't Throw It, Grow It! will appeal both to committed recyclers and to anyone who wants to find magic in the mundane — from parents and teachers looking to instill a sense of wonder in children, to the houseplant enthusiast seeking to create a one-of-a-kind Eden right in her kitchen.

This tidy kid-friendly book has 122 pages crammed with activities and information on chemistry as well as support material in each chapter focused onWords to Know, Did You Know? and What's Happening? as well as a brief list of Supplies and boldly numbered steps of how to do each project. Featured projects (they do not call them experiments) include Make Your Own Buckyball; Make a Model of a Water Molecule; Separate Leaves and Dirt; Make a Chroma-Color Bookmark; Extract Iron from Cold Cereal; Make an AlkaSeltzer Rocket; Make Rusty Shapes; Clean Your Pennies; Make a Foamy Volcano; Make Eggs Lose Their Shells; Make Invisible Messages; Make Your Own Crystals; Make Rock Candy; Make a Candy-Glass House; Make a Wave Tank; Layering Liquids; Make an Octopus Diver; Put an Egg in a Bottle; Exploding Mentos; Swimming Raisins; Stretchy Taffy; Prove that Hot Water Freezes Faster Than Cold Water; Make Vanilla Ice Cream; Make Oobleck and Silly Putty. Lots of science information is mixed with the how-to of the projects and there is hardly a blank space on a page anywhere in the book. Lots of sidebars on related topics, small factoids that tie to the subject fill each chapter to the tippy top. There are 10 chapters: Atoms, Mixtures, Reactions, Acids/Bases, Solids, Liquids, Gases, Change of State, Polymers, Water as well as a glossary, index, extensive list of websites, and book resources. Most projects are safe enough for kids to do without too much adult supervision, and there is a great deal of information packed into this volume. The illustrations don't have kids in them, so it could even be used with adults. A very nicely done and reasonably priced collection.
