Everyone in this part of Florida knows that when freezing temperatures are forecast you go through your linen closet and get every old sheet, blanket and towel - oh, and tarps, too - to encase your delicate, tropical landscaping. The covering is supposed to go to the ground to keep the warmth in and around the plants. These are (or were) palms, crotons and liriope.
