When to plant Gypsophila in Temperate Australia

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

Sow gypsophila direct across a long window from February to November, which lets you fit successional patches through autumn, winter and spring in the mild temperate zone. Cover the seed at 5 mm; it germinates quickly in 10 to 20 days and races to its cloud of tiny white flowers in just 70 to 80 days. Thin or space plants 20 to 30 cm apart with rows 30 to 45 cm wide. Hardy and quick, this annual baby's breath (Gypsophila elegans) makes an airy filler and a classic cut flower for gardens around Melbourne, Adelaide and Perth.

Growing notes

Annual gypsophila is fast and easy, and the generous February-to-November window means you can sow small batches every three to four weeks for a continuous supply rather than one big flush. It dislikes transplanting, so always sow direct where it is to flower. Full sun is essential; in shade the stems flop and flowering is thin.

The name is the clue to its one firm requirement: gypsophila wants sweet, alkaline, free-draining soil. The common failure in temperate gardens is stunted, sulky plants grown in acidic, heavy or wet ground. If your soil is on the acid side — as much of coastal Sydney and Perth is — work in a little garden lime before sowing and make sure drainage is sharp. Waterlogged roots rot fast.

Because each plant is short-lived and flowers only for a few weeks, succession is the whole game. A single sowing gives you a brief show and then goes over; staggered sowings keep the airy white haze going for months. Provide light twiggy support or grow it through neighbouring plants, as the fine stems fall over in wind and rain. Cut for the vase when about half the tiny flowers on a stem are open for the longest vase life.

Common questions

when can I sow gypsophila in a temperate garden

The window is long, from February to November, so you can sow through autumn, winter and spring. Sow small batches every three to four weeks for a continuous supply, since each plant flowers only briefly.

why is my gypsophila not thriving

The usual cause is acidic or poorly drained soil. Gypsophila wants sweet, alkaline, free-draining ground, so add a little garden lime before sowing if your soil is acid, and make sure it never sits wet.

how quickly does gypsophila flower from seed

It is fast, flowering in just 70 to 80 days from sowing, with germination in 10 to 20 days. This speed is why successional sowing works so well for a long season of blooms.

does gypsophila need staking

The fine stems tend to flop in wind and rain, so light twiggy support helps, or grow it through neighbouring plants that hold it up. Full sun also keeps growth sturdier than shade.
