Whether or not you believe in global warming, the past 20 years in Virginia have been getting noticeably hotter and drier. Internationally acclaimed horticulturist Ian Robertson (Piedmont Virginia CC) pays careful attention to plants in his work and says we can already see changes in the fauna of Virginia. While the issue is a global one, there are things we can do locally in our gardens to help.

Also featured: From acacia, the wood of the tabernacle, to wormwood, whose bitter leaves flavor such alcoholic drinks as absinthe, Lytton Musselman (Old Dominion University) explores the plants of the holy lands. Musselman is the author of Figs, Dates, Laurel, and Myrrh: Plants of the Bible and the Quran.
