Bossiaea cinerea is commonly known as the Showy Bossiaea – is a charming Australian native shrub from the pea family (Fabaceae), known for its delicate foliage and for the sheer numbers or brilliant pea-shaped flowers. Native to the south-west of Western Australia, it grows naturally in open forests, heathlands, and woodlands, adding a splash of golden-yellow and orange-red colour to the landscape during its flowering season.

This species is part of the rich flora of south-western Australia, a region famous for its incredible biodiversity. It is perfectly adapted to the area’s sandy, well-drained soils and dry summers, making it an ideal choice for Australian native and water-wise gardens.

Bossiaea cinerea is not edible and is grown purely as an ornamental species. However, it plays an important ecological role by fixing nitrogen in the soil, improving soil fertility, and supporting native insects and pollinators through its abundant flowers.

This plant is often used in native gardens, restoration projects, and bushland plantings for its beauty, hardiness, and value to wildlife. The attractive pea flowers are rich in nectar and pollen, drawing bees, butterflies, and native insects. Its compact growth habit also makes it useful as a low hedge or border plant in native-themed gardens.

How it Grows
Bossiaea cinerea is a small, bushy shrub, typically growing to around 1 to 2 metres in height and width. It produces slender branches with small, narrow leaves and masses of bright yellow flowers with orange to red centres during winter and spring. It prefers full sun to partial shade and well-drained soils, particularly sandy or gravelly types. Once established, it is very drought-tolerant and low-maintenance, requiring little more than the occasional light prune to maintain shape.

How to Grow From Seed:

Seeds have a hard outer coat and benefit from pre-treatment to encourage germination. The best method is to pour boiling water over the seeds and allow them to soak overnight before sowing.

Sow treated seeds in a free-draining native seed-raising mix and cover lightly.

Keep moist but not wet.

Germination usually occurs within 3–6 weeks.

Once seedlings are large enough to handle, transplant into pots and grow on until well established. Plant out into the garden in a sunny, open spot with well-drained soil.

Like many Australian natives, Bossiaea prefers low-phosphorus fertilisers and will reward you with years of colour and resilience.
