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.

Gulf County, Florida is in USDA Zone 9b. The average last spring frost is February 25 and the first fall frost is November 28, giving you a growing season of approximately 276 days.

At an elevation of 313 feet, Gulf County receives approximately 51.7 inches of rainfall annually with predominantly sand soil. Summer highs average 92°F, providing good warmth for Salvia during the growing season. 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 ~1,520 GDD — county provides 5,263 GDD Excellent fit

Sandy soil in Gulf County dries quickly — mulch Salvia with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

General growing tips

Start indoors 8-10 weeks before last frost; seeds need 65-70°F soil and light to germinate (surface-sow, do not cover). Transplant after last frost when soil has warmed. Salvia is frost-sensitive — even a light frost kills plants. Pinch spent spikes to encourage continued bloom. Tolerates heat and humidity well once established.
