Achira in Zone 6a & 6b
Canna edulis
When to plant achira in zone 6b
Zones 6a and 6b 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 | Feb 28–Mar 7 |
|---|---|
| Direct sow / transplant outside | May 9–May 16 |
| Estimated harvest | Nov 5–Nov 12 (~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 6's season
