When to plant achira in zone 9b
Zones 9a and 9b 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 21–Dec 28 |
|---|---|
| Direct sow / transplant outside | Mar 1–Mar 8 |
| Estimated harvest | Aug 28–Sep 4 (~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.
