When to Plant Borage in Vermilion Parish, LA

Vermilion Parish, Louisiana is in USDA Zone 9a. The average last spring frost is February 13 and the first fall frost is December 5, giving you a growing season of approximately 295 days.

At an elevation of 430 feet, Vermilion Parish receives approximately 54.1 inches of rainfall annually with predominantly sandy loam soil.
