They could come back from the roots.
Since this thread started, I have been reading about spider plant care on the web. It's interesting all the rules about their care. Allow the soil the be completely dry before watering, no direct sun, no tap water, allow to be bound bound. Mine are in the ground all year and get very little care other than occasional watering. Mine are watered by hose (tap water), in the ground so not root bound, get extreme temperatures (near 100 to mid 20's), a few hours of full sun, and are wet all winter. Although they look rough in the winter, they bounce back and look beautiful during the growing season.
