Salvia splendens is a tender perennial from Brazil grown as a warm-season annual throughout the US. Its vivid, upright flower spikes in brilliant red, purple, and coral are irresistible to hummingbirds, bees, and butterflies. One of the longest-blooming annuals in the landscape — plants bloom from early summer until hard frost with minimal deadheading required.

Leon County, Florida is in USDA Zone 9a. The average last spring frost is March 11 and the first fall frost is November 21, giving you a growing season of approximately 255 days.

At an elevation of 250 feet, Leon County receives approximately 53.9 inches of rainfall annually with predominantly sand soil. Summer highs average 95°F, so Salvia may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Salvia will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Salvia root diseases.

Salvia 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.

Salvia needs ~1,700 GDD — county provides 5,418 GDD Excellent fit
