Can Lagerstroemia indica root live if it freezes to death?

If the whole plant freezes to death, it can't live. If only part of the ground is dead, but the underground roots continue to grow, they will continue to sprout and grow next spring.

Lagerstroemia indica can be transplanted in winter dormancy in Jiangnan, and it is colder in Xuchang in winter. At this time, the transplanted Lagerstroemia indica is still naked, and the survival rate is low.
