Malabar spinach is a tropical vine with thick, succulent leaves that taste similar to spinach. Unlike true spinach, it thrives in heat and humidity.

Orleans Parish, Louisiana is in USDA Zone 9b. The average last spring frost is February 20 and the first fall frost is November 23, giving you a growing season of approximately 276 days.

Summer highs average 101°F, so Malabar Spinach may need afternoon shade and extra watering during peak heat.

Malabar Spinach Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Malabar Spinach needs ~1,609 GDD — county provides 7,132 GDD Excellent fit
