Canna edulis
When to plant achira in zone 10b
Zones 10a and 10b 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 | Dec 5–Dec 12 |
|---|---|
| Direct sow / transplant outside | Feb 13–Feb 20 |
| Estimated harvest | Aug 12–Aug 19 (~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 10's season
Zone 10b's frost-free window runs about 324 days, from January 30 to December 20. Achira needs about 180 days from sowing to first harvest.
