Anna Pavord’s beautiful Bulb (Octopus, $39.99) will give you new insight into these plants and inspire you to do some serious digging. Though not a book you would take out to the garden, this volume provides both encyclopedic notes on different bulbs, corms, and tubers, including an insightful introduction with a brief history, and a substantial and instructive “How to Grow Bulbs” section. Full of lush, full-color photos, this is the perfect gift for any gardener, weathered or novice.
