Planting Zone Map
An updated Plant Hardiness Zone Map (see below) was just released (November 2023) and on average, low temps are about 2.5 degrees warmer. The Little Rock area zone has not changed but there are half zone changes north (no zone 6b areas, expanded 8a area) and south of us (now a sizable area of zone 8b). This is based on the average extreme minimum temps over the past 30 years. A huge increase in weather stations, making information more precise, likely contributed.
Below is the 2012 map, which was based on data through 2005.
