  1. A greenhouse covering can be glass or something more durable, like polyethylene, polycarbonate or fiberglass.
  2. One of the earliest greenhouses, known as a specularium, was built around A.D. 30 to satisfy Roman Emperor Tiberius’ craving for cucumbers out of season. During cold months, cucumber beds were covered with sheets of mica, a translucent stone.
  3. The ideal temperature range for most greenhouse crops is 55 to 60 degrees at night and 70 to 75 degrees during the day.
  4. The French called their early greenhouses orangeries, since they were built to protect orange trees. Today, in English, “orangery” is still sometimes used as a synonym for “greenhouse.”
  5. Andrew Faneuil, a wealthy Bostonian of the early 1700s, grew fruit in what some believe to be the first true greenhouse in the United States.
  6. George Washington grew pineapples, his favorite fruit, in a Mount Vernon greenhouse known as a pinery.
  7. By 1825, greenhouses were becoming more common throughout northern regions. Many were heated by furnaces;  others were built into the earth and warmed by south-facing windows, a design still practical today.
