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.

Hendry County, Florida is in USDA Zone 10a. The average last spring frost is January 14 and the first fall frost is April 15, giving you a growing season of approximately 91 days.

At an elevation of 403 feet, Hendry County receives approximately 55.9 inches of rainfall annually with predominantly sand soil. Summer highs average 89°F, providing good warmth for Snapdragon during the growing season. 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 ~1,424 GDD — county provides 6,113 GDD Excellent fit

Growing Tips for Snapdragon in Hendry County

Direct sow Snapdragon outdoors after January 14 in Hendry County when soil has warmed and frost danger has passed.

Sandy soil in Hendry 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.
