A Christmas Herbarium: The Nature and Culture of our Favorite Holiday Plants
The Festive season is upon us. Many of us are busy hanging wreathes, decorating trees, and putting up mistletoe in doorways for that holiday smooch. If it's Christmas you celebrate, most of our traditions go far further back than inflatable characters out of Rudolph the Red-Nosed Reindeer on the front lawn. And one thing that... Continue Reading →
