Climate matters. This page is a practical baseline. Confirm cultivar, local frost/heat conditions, mature size and regional restrictions before planting.

Growing directions
Sow seeds 1/4 in deep directly in their final location in rich, well-drained soil; anise develops a taproot that transplants poorly. Thin to 6–12 in apart once seedlings are established, and stake plants in exposed sites as they can be top-heavy when in flower. Anise needs a long, frost-free season to set seed—at least 120 days—so start as early as possible in cool climates. Harvest umbels when seeds begin to turn gray-green, cutting whole heads into paper bags to catch seeds as they ripen.
