Snapdragons (Antirrhinum majus) are classic cool-season annuals whose upright spikes of dragon-lipped flowers are among spring's most dramatic displays. Tolerating light frosts, they bloom from early spring until summer heat shuts them down — then often revive in fall. In zones 9-11 they are grown as fall-planted winter annuals and may re-seed to naturalize.

Franklin County, Florida is in USDA Zone 9a. 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 487 feet, Franklin County receives approximately 59.9 inches of rainfall annually with predominantly sand soil. Summer highs average 96°F, so Snapdragon may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Snapdragon will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Snapdragon root diseases.

Snapdragon 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.

Snapdragon needs ~1,870 GDD — county provides 6,094 GDD Excellent fit

Growing Tips for Snapdragon in Franklin County

Direct sow Snapdragon outdoors after February 25 in Franklin County when soil has warmed and frost danger has passed.

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

General growing tips

Start indoors 10-12 weeks before last frost; seeds need light to germinate — press into moist medium and do not cover. Transplant after hardening off, even if light frosts remain. Pinch seedlings once to encourage branching. Deadhead to prolong blooming. In zones 8-11, sow in fall for a winter-to-spring show. Tall varieties (24-36") make excellent cut flowers.
