When to Plant Snapdragon in Collier County, FL
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.
Collier County, Florida is in USDA Zone 10b. The average last spring frost is January 12 and the first fall frost is April 15, giving you a growing season of approximately 93 days.
At an elevation of 185 feet, Collier County receives approximately 61.3 inches of rainfall annually with predominantly sand soil. Summer highs average 85°F, providing good warmth for Snapdragon during the growing season.
