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.

Limestone County, Alabama is in USDA Zone 8a. The average last spring frost is April 5 and the first fall frost is October 29, giving you a growing season of approximately 207 days.

At an elevation of 200 feet, Limestone County receives approximately 54.7 inches of rainfall annually with predominantly clay loam soil. Summer highs average 93°F, providing good warmth for Snapdragon during the growing season. Clay soil retains moisture well for Snapdragon, but amend with compost to improve drainage and prevent root rot. 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 ~1,679 GDD — county provides 4,088 GDD Excellent fit
