When to plant achira in zone 8b
Zones 8a and 8b 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 | Jan 28–Feb 4 |
|---|---|
| Direct sow / transplant outside | Apr 8–Apr 15 |
| Estimated harvest | Oct 5–Oct 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 8's season
