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.

Clay County, Alabama is in USDA Zone 8a. The average last spring frost is March 29 and the first fall frost is October 31, giving you a growing season of approximately 216 days.

At an elevation of 109 feet, Clay County receives approximately 60.7 inches of rainfall annually with predominantly clay loam soil. Summer highs average 91°F, providing good warmth for Snapdragon during the growing season.

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 ~1,551 GDD — county provides 3,942 GDD Excellent fit

Growing Tips for Snapdragon in Clay County

Direct sow Snapdragon outdoors after March 29 in Clay County when soil has warmed and frost danger has passed.

With Clay County's clay soil (34% clay), work in 3-4 inches of compost before planting Snapdragon. Avoid tilling when soil is wet to prevent compaction.

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.
