Achira in Zone 11a & 11b
Canna edulis
When to plant achira 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. Achira tolerates either.
| Start indoors | Nov 6–Nov 13 |
|---|---|
| Direct sow / transplant outside | Jan 15–Jan 22 |
| Estimated harvest | Jul 14–Jul 21 (~180 days after planting) |
Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 4-8 ft.
Achira is a rhizome crop related to the ornamental canna lily, with similar-looking foliage but grown for its large, starchy rhizomes rather than its flowers.
How achira 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.
