Is lavender a perennial?
Yes, lavender typically comes back every year in suitable climates. Lavender is a perennial plant, which means it regrows each spring if it’s grown in the appropriate USDA hardiness zones (typically 5 to 9). To keep lavender alive in winter, you need to protect it from the cold by adding a layer of mulch around the base of the plant, reducing watering to minimal or stopping watering altogether, and adding a cover for extreme snow events or long periods of temperatures below freezing.
