Move snapdragon into the garden
Frost risk is low now in Zone 2a. If you've been covering beds overnight, you can stop.
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.
In Zone 2a, the average last spring frost is around May 30 and the first fall frost is around September 1, giving you a growing season of approximately 94 days.

Growing Tips for Snapdragon in Zone 2a
Zone 2a has a short growing season (~94 days). Start Snapdragon indoors early and use season-extension techniques like row covers and cold frames.
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.
