TWO AND A half years ago, after a lifetime of gardening in the Great Lakes Region, I moved with my husband down to Williamsburg, Virginia. I went from Zone 5 to Zone 7, almost Zone 8. The average year down here has about three times as many days with highs over 90°F (32°C) as what I was used to in Michigan. My new home town gets an average of 47 inches (120 cm) of precipitation a year compared to the 36 inches (91 cm) I had known. In short, it is hot and wet down here, not exactly the preferred climate of many alpine plants.
