Celosia in Zone 2a & 2b
Celosia argentea
When to plant celosia in zone 2b
Zones 2a and 2b share the same average frost dates in our data, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Celosia tolerates either.
| Start indoors | Apr 1–Apr 8 |
|---|---|
| Direct sow / transplant outside | May 27–Jun 3 |
| Estimated bloom | Aug 15–Aug 22 (~80 days after planting) |
Spacing: 2 per square foot (square-foot-gardening spacing). Mature height: 1-2.5 ft.
Celosia is a dense, upright bloomer (either the crested "brain" type or the feathery plume type) that handles heat and drought well once it's up and growing, making it one of the more forgiving flowers on this list.
How celosia fits zone 2's season
Zone 2b's frost-free window runs about 104 days, from May 20 to September 1. Celosia needs about 80 days from sowing to first harvest.
