When to plant Anise in Cool Australia

Cool zone — applies to Hobart, Canberra, Ballarat, Orange, Armidale and similar areas. Growing elsewhere? Temperate · Subtropical · Tropical · Arid.

Anise is not recommended for cool climates, and there is no reliable sowing window here. This half-hardy herb needs a long, warm growing season of around 120–150 days to flower and ripen its aromatic seed, which the short frost-free gap in districts like Hobart, Ballarat and Orange rarely provides. Even sown at the very start of spring, plants tend to be cut short by the first autumn frost before the seed heads fill. Rather than fight the season, cool-climate gardeners are better served by growing anise in a warm, sheltered spot purely for foliage, or choosing a hardier aromatic such as dill or fennel instead.

Growing notes

The core problem is time and temperature. Anise wants a long, hot, uninterrupted run of 120–150 days from sowing to seed, and it resents transplanting and cold checks. In cool districts like Canberra and Armidale, the frost-free window between spring and autumn is often barely long enough, and any cold snap stalls the plant just as it should be flowering.

Why it fails here: sown after the last frost, the plant grows slowly through a cool spring, flowers late, and then meets the first autumn frost before the seed has ripened and dried. Damp cool-climate autumns compound the problem, encouraging the seed heads to rot rather than cure.

If you want to try anyway, give it your warmest, most sheltered, sun-trap position, ideally against a north-facing wall, and start seedlings early under cover to steal a few weeks. Even then, treat any ripe seed as a bonus and be prepared to harvest the plant for its aniseed-flavoured leaves instead.

A more dependable path in a cool climate is to grow a hardier aromatic. Dill, fennel and caraway all tolerate cool conditions far better and give you similar sweet, aniseed notes without the race against frost.

Common questions

can you grow anise in Tasmania

It is difficult. Anise needs 120–150 days of warmth to ripen seed, and Tasmania's cool, short frost-free season rarely delivers that. You may get leaves in a warm sheltered spot, but reliable seed is unlikely.

why is anise hard to grow in cool climates

Because it is half-hardy and needs a long warm season. In cool districts the plant flowers too late and is caught by autumn frost before the seed ripens, and damp autumns can rot the seed heads.

what can I grow instead of anise in a cold area

Try dill, fennel or caraway. All tolerate cool conditions far better than anise and offer similar sweet, aniseed flavours without needing a long hot season to set seed.

will anise survive frost

Anise is only half-hardy, so a hard frost will damage or kill it, and even a light frost checks its growth. This is why it struggles to complete its long life cycle in frost-prone cool districts.
