Celosia in Zone 11a & 11b
Celosia argentea
When to plant celosia in zone 11b
Zones 11a and 11b 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 | Nov 13–Nov 20 |
|---|---|
| Direct sow / transplant outside | Jan 8–Jan 15 |
| Estimated bloom | Mar 29–Apr 5 (~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 11's season
Zone 11b is frost-free in this dataset, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
