Identification of Trees and Shrubs in Winter Using Buds and Twigs [PDF ebook] 

For many plant lovers, winter seems like a lost time. The bursts of color and distinctive leaf shapes disappear, leaving what seems like ambiguous branches. But there is no need for botanical enthusiasts to hunker down until spring. What we overlook as "dead trees" are simply shoots covered up for the season. If we look closer, we’ll see that trees and shrubs have distinct shapes to their buds and twigs that allow them to be classified reliably in winter.While most books focus on identifying leaves and other seasonal characteristics, this practical guide is one of the few that will allow gardeners to identify trees and shrubs while they are in their dormant state. It covers more than seven hundred species and includes easy-to-use illustrated identification keys. More than 1, 400 color images make it even easier to spot the distinctive pieces of these plants.
