Rue is a bitter, aromatic perennial herb with bluish-green foliage used historically in medicine and as a pest deterrent. Handle with care as its sap can cause skin irritation.

Marion County, Florida is in USDA Zone 9a. The average last spring frost is February 15 and the first fall frost is December 1, giving you a growing season of approximately 289 days.

At an elevation of 244 feet, Marion County receives approximately 54.1 inches of rainfall annually with predominantly sand soil. Summer highs average 97°F, so Rue may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Rue will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Rue root diseases.

Rue 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.

Rue needs ~1,820 GDD — county provides 6,597 GDD Excellent fit
