Snapdragon in Zone 7a & 7b
Antirrhinum majus
When to plant snapdragon in zone 7b
Zones 7a and 7b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Snapdragon needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Feb 6–Feb 13 |
|---|---|
| Direct sow / transplant outside | Apr 3–Apr 10 |
| Estimated bloom | Jul 2–Jul 9 (~90 days after transplanting) |
Spacing: 2 per square foot (square-foot-gardening spacing). Mature height: 1-3 ft.
Snapdragons are one of the few flowers here that tolerate a light frost, which makes their planting window a little more forgiving than most, though the long indoor lead time before that still catches people off guard. What you're waiting for is a 1- to 3-foot spike of two-lipped, dragon-mouth blooms in almost any color you'd want.
How snapdragon fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Snapdragon needs about 90 days from transplant to first harvest.
