Have you planted any sunflowers? The flowers track the sun throughout the day.
I've not noticed it in our back yard, but I remember seeing an entire field of them do it in Wisconsin!
I really can't believe everything is still alive. They're growing real slow, but they're very much alive! I cover them with the floating row cover stuff over night and went out to find it covered in frost. Once the sun hits the garden, no matter the outside temperature, I uncover them and allow the sun to warm the soil. Then, at dusk, I go out and cover it all back up again.
Nothing has died. I have small spinach, lettuce, collards, carrots, and turnips...very small, but alive!
The garlic looks like it's in heaven, though, and is 6-8" tall already!
