A couple hundred feet can make all the difference in the world sometimes. The first two pictures are typical of my work gardens in the back today.
Now, fast forward to a mixed annual/preannual garden in the front that's facing Lake Michigan but in wide open unprotected space from sun up to sun down. It's like steeping into a different world. There are about 75 to 100 lily plants in here of Asiatic, Trumpet, Oriental, Oriental/Trumpet, Longiflorum/Oriental, and Trumpet/Asiatic. Not a single plant was touched by frost. The pictures are typical of all the lilies in there.
In this last picture, you'll my black Jeep in the upper hand corner. My work gardens are about 200 feet to the left of the black Jeep
