When to plant Brachycome in Temperate Australia

Temperate zone — applies to Sydney, Melbourne, Adelaide, Perth, Newcastle and similar areas. Growing elsewhere? Cool · Subtropical · Tropical · Arid.

Sow brachycome direct from August to December, scattering the fine seed just 3 mm deep in a sunny, well-drained bed. Germination takes 10–20 days once the soil warms, so an early August sowing in Melbourne or Adelaide may sit quietly until spring properly arrives. This half-hardy Swan River daisy reaches flowering size in about 110–130 days, forming low mounds smothered in mauve, blue and white daisies. Thin or space plants 15–20 cm apart in rows the same distance apart so the cushions knit together. A light, quick-draining spot near a path or the front of a border suits it best.

Growing notes

Brachycome is an easy filler for temperate gardens, but it earns its keep only in full sun and sharp drainage. In the milder coastal parts of Sydney and Newcastle you can start sowing in August; inland Melbourne and Adelaide gardeners are safer waiting until September, once the worst frost risk has passed, since young seedlings are only half-hardy.

The most common failure here is legginess and rot. Sown into heavy, wet winter soil, seed either fails to strike or the seedlings damp off at the base. If your bed stays soggy, raise it slightly or work through coarse sand and compost before sowing, and resist the urge to overwater once plants are up. The other issue is a short, disappointing show: in rich soil or partial shade the plants sprawl and flower sparsely. Keep the fertiliser light and give them the sunniest position you have.

Once established they are drought-tolerant and self-clean reasonably well. A light shear after the first flush of daisies fades will push a fresh wave of blooms through summer. In a hot, dry Adelaide summer a weekly deep soak keeps them going rather than letting them crisp off.

Common questions

When should I plant brachycome seeds in Melbourne?

Sow direct from September to December once the soil has begun to warm and heavy frosts have passed. August sowings are possible in milder coastal spots but seed will simply wait for warmth before germinating. Aim for a sunny, free-draining bed.

How long does brachycome take to flower from seed?

Allow roughly 110–130 days from sowing to a full flush of daisies. Seed germinates in 10–20 days, then the plants mound up before blooming through late spring and summer. Earlier sowings give a longer flowering season.

Why is my brachycome leggy and not flowering?

Legginess and poor flowering almost always come from too much shade or overly rich, moist soil. Move it to full sun, ease off the fertiliser and let the soil dry between waterings. A light shear after the first flush encourages a denser, more floriferous mound.

How far apart should I space brachycome plants?

Space plants 15–20 cm apart, with rows 15–20 cm apart, so the low cushions grow together into a continuous carpet. Closer spacing crowds the roots and worsens the risk of rot in damp weather.
