The general advice on calla lily is to take the tubers indoors if you are north of zone 8. There are many factors that affect soil temperature within yards, the so-called micro-climates. Bring right next to brick or stone will likely keep soil warmer. So will mulching but only to a limited extent. Calla, unlike tulips, are planted shallowly and will turn to mush if frozen. There are many small spring bulbs, like Siberian squill, that aren't affected by being frozen. However, calla lilies are tropical plants. It is not adapted to cold weather. It is up to you whether you want to take the risk of losing them. I love my calla and get lots of compliments about them. Because they are shallowly planted, they are easy to lift in the fall and store. Here's how: https://www.gardeningknowhow.com/ornamental/bulbs/calla-lily/calla-lily-winter-care.htm
