Impatiens walleriana
When to plant impatiens 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. Impatiens needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Jan 30–Feb 6 |
|---|---|
| Direct sow / transplant outside | Apr 24–May 1 |
| Estimated bloom | Jul 8–Jul 15 (~75 days after transplanting) |
Spacing: 2 per square foot (square-foot-gardening spacing). Mature height: 0.5-2 ft.
Impatiens flowers reliably in shade, which almost nothing else here does. It also carries a disease problem worth understanding before you plant a whole bed of it.
How impatiens fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Impatiens needs about 75 days from transplant to first harvest.
