I live in Utah, north of Salt Lake. Can I leave my calla lily in the ground through winter? I plan on planting it on the southern end area of my house, with some shade, but mostly sun.
Leaving Calla Lily in Ground
Certified GKH Gardening Expert
Calla lilies are not cold hardy and only survive in the ground in USDA plant hardiness zones 8 or higher. Utah ranges from zone 4 in the northeast to 8 in the southwest. Therefore, I do not think Calla Lilies would successfully overwinter in the ground where you live.
