When to Plant Snapdragon in North Carolina

Growing Snapdragon in North Carolina: Complete Guide

Snapdragon (Antirrhinum majus) is a warm-season crop that needs a head start indoors before North Carolina's last frost. Depending on your zone, North Carolina gardeners start seeds indoors between December 26, 2026 (Zone 9a) and February 18, 2027 (Zone 6b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because North Carolina stretches across 6 USDA hardiness zones (6b, 7a, 7b, 8a, 8b, 9a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 60 days to maturity, Snapdragon needs the indoor head start that North Carolina's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Snapdragon requires full sun to partial shade and regular (1-2 inches/week) moisture. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
