Louisiana Planting Zones

Louisiana planting zones

Because it has low lying topography and low latitude, Louisiana’s humid subtropical climate weather patterns means hot, long, very humid summers and relatively mild, short winters. This makes the Louisiana planting zones pretty consistent across the state. The state’s climate is overwhelmingly influenced by the Gulf of Mexico, which is no more than 200 miles away at any point. Rain is common throughout the entire year, but summers are wetter than the rest of the year. Thunderstorms result from the heat of summer days and there are often quick but intense tropical downpours. Winters are generally fairly warm in the southern parts of the state. The northern regions are mildly cool, with average lows remaining well above freezing and average highs at right around 59 degrees. The state regularly sees tropical cyclones and major hurricanes. 

The United States is divided into sections known as planting zones. These zones help define and dictate both what types of plants will grow well, as well as when to plant them. Louisiana planting zones are in the 8a to 10a range. Check out Gilmour’s Interactive Planting Zone Map to see which zone you are in. The southern part of the state, closest to the Gulf of Mexico, is on the warmer end of the range. It is very important to know what Louisiana planting zone you will be planting a garden in so you can decide on plants that have the highest chance for success in your area. Reference Louisiana growing zones ranges to know exactly when to plant each type of vegetable, plant or flower you want to grow, too. It is safe to plant anything rated for the zone a plant will be growing it or lower. So, if planting in zone 8a, plants rated for zones 1 to 8 should be able to survive winter conditions.

With its tropical climate and abundance of rainfall, many gorgeous flowers and tropical plants do very well all over the state. However, do be sure to seek out heat- and humidity-tolerant plants for the best show and chance of survival. Wishbone flower, angelonia, pentas, begonias, coleus, impatiens, blue daze and narrow-leaf zinnia all do well in the area. Plant tomatoes, peppers, eggplant, okra and beans in a vegetable garden that will produce a bounty of vegetables to enjoy all season long.
