All of Little Rock's mapped ZIP codes fall in the same hardiness band, Zone 8a.

These are 50%-probability averages modeled from Little Rock's USDA hardiness zone and regional climate normals — not a single-station reading. In a typical year the last spring frost will have passed by March 30, but a colder-than-average year can run 1-2 weeks later. Plant tender crops (tomatoes, peppers, basil) once both soil and night temperatures are consistently warm — a thermometer beats the calendar.

Little Rock, Arkansas sits in USDA Zone 8a, with roughly 216 frost-free days between an average last spring frost around March 30 and a first fall frost around November 1. That is a long season — succession-sow through summer and run a full fall crop; heat-sensitive greens still need spring/autumn timing. Little Rock lies near 34.7°N; higher-latitude gardens get longer midsummer days but a tighter shoulder season at this zone.

Local microclimate notes

Zone tables give you the average — but Little Rockgardens vary. South-facing walls and paved areas can run a full half-zone warmer than the published rating. Low-lying spots, frost pockets, and shaded north sides can run colder. If you've gardened here a few seasons, your own frost record — the last time you actually got frost damage — beats any national average.

Source and methodology

Hardiness zone from the USDA Plant Hardiness Zone Map (2023 revision). Frost-date and growing-season figures are modeled from Little Rock's USDA hardiness zone and regional NOAA 1991-2020 climate normals — zone-level estimates, not a per-station record, so treat them as planning guidance and confirm against your own local frost history. Crop recommendations draw on US Cooperative Extension references, curated by the Growli editorial team. Last reviewed June 2026.
