Sturt’s Desert Pea, Swainsona formosa, is one of Australia’s most iconic wildflowers, known for its spectacular blood-red petals marked by a glossy black centre. It is native to arid regions of Central and Western Australia and has long been admired by Indigenous communities, who used the plant symbolically and recognised its presence as an indicator of seasonal change. It is now the floral emblem of South Australia and is treasured for its dramatic beauty and resilience in tough conditions.

Sturt’s Desert Pea holds cultural significance rather than culinary value. It is valued today as a feature ornamental plant and is popular with gardeners who love native species and bold displays of colour. The flowers are unforgettable, appearing on low trailing stems that spread across dry ground, often blooming after seasonal rains. The plant forms silvery-grey foliage that contrasts beautifully with the intense red flowers.

Sturt’s Desert Pea grows naturally in hot, dry regions with sandy or well-drained soils. It thrives in full sun and is adapted to long periods of drought. Once established, it is surprisingly tough, though it does not tolerate waterlogged soil. It is often short lived in cultivation, but with the right conditions it can flower generously and reseed itself. Gardeners in cooler or wetter coastal areas may find it easier to grow in raised beds or well-draining containers to mimic its natural environment.

How to Grow From Seed:

Sturt’s Desert Pea seeds have a very hard coating and need pre-treatment to germinate well. The most common method is to gently nick or rub the seed coat with sandpaper, or pour boiling water over the seeds and leave them to soak overnight.

Sow treated seeds about one centimetre deep into a sandy, free draining seed raising mix or direct into the garden. Keep moist but never soggy. Germination usually takes one to three weeks in warm conditions.

Transplant seedlings carefully once they are large enough to handle, avoiding root disturbance.

Plant into a sunny position with excellent drainage.

Water sparingly once established and avoid rich fertilisers, particularly those high in phosphorus.

In the right setting, Sturt’s Desert Pea will reward you with spectacular flowers and the unmistakable look of the Australian outback.
