Summary: Today we celebrate an eighteenth-century man who was a friend of many famous gardeners. And, the Danish surgeon associated with many wonderful plants from the Himalayas. We'll learn about the Swedish botanist who had a thing for algae and the man who started the only arboretum between the Mississippi River and the Rocky Mountains. Today’s Unearthed Words feature poems and prose about winter's cold.
