10 Australian Native Purple Flowers for Your Garden

Aussie natives are a great choice to add both beauty and biodiversity to your garden.

Our native plants have a natural beauty that has evolved over thousands of years while adapting to the Australian climate.

The range of purple flowering plants here in Australia is vast and varied, so we’ve decided to take a closer look at some of our favourites.

Native Hibiscus (Alyogyne huegelii)

The native Hibiscus is a medium/large-sized shrub reaching about two metres tall and wide. Its beautiful large purple flowers appear in Spring and Autumn.

This plant can mostly be found in Western Australia and is perfect for coastal areas.

This Native Hibiscus is a great option for any garden enthusiasts who want to landscape their space with something that adds a pop of colour and requires minimal maintenance.

Showy Honey Myrtle (Melaleuca nesophila)

Showy Honey Myrtle is a beautiful small evergreen tree that may eventually reach 5 metres in height and 4 metres in width.

It has elongated oval leaves and the globular purple flowers bloom in spring, winter and summer. It will grow in almost any soil but prefers a sunny spot.

Also known as Western Honey Myrtle, this native flower is endemic to the south of Western Australia.

Native violet (Viola hederacea)

Most Australian gardeners will be familiar with the native violet. It’s one of those plants that will grow almost anywhere and is particularly great for spots that are heavily shaded.

It will spread around the garden and pop up quite readily to form a fairly dense mat of dark green foliage. Viola hederacea spreads through underground runners and is the perfect ground cover plant for difficult areas where nothing else will grow.

The lovely purple and white flowers appear through most of spring and summer. These flowers can add some much-needed colour to darker spots in your garden.

Australian violets like moist soil and are perfect for planting under native trees and in rockeries. The only thing that they don’t like is dry conditions.

Even though this plant can spread profusely, it’s easy to keep it under control and any plant sections that you pull out can be planted elsewhere in the garden.

Purple Coral Pea, Happy Wanderer (Hardenbergia violacea)

Hardenbergia violacea is an evergreen Australian native climbing plant with twining stems.

It’s indigenous to the Adelaide region of South Australia but can also be found in VIC, NSW, TAS and QLD.

Hardenbergia violacea flowers are pea-shaped and grow in clusters, with colours ranging from light pink to deep purple, and occasionally white.

In spring, they bloom and cover the top of the bush in a stunning display of colour. They’re also perfect for pollinators like bees and butterflies.

Blue Flax Lily (Dianella longifolia)

You can easily identify this native grass by its long flower spikes that feature tiny purple to blue flowers in late spring through to summer.

After flowering, the plant produces purple berries that are edible. The leaves are bright green and strappy. 

This native grass is both frost and drought-tolerant and can be successfully grown in most soils. It will grow in full sun and part shade.

Each plant will reach a height and width of 1 metre. Like most native grasses, it can be cut back when it needs a tidy-up or left to grow naturally.

Claw Flower (Melaleuca pulchella)

Claw Honey-myrtle, or Melaleuca pulchella, is a small Australian native shrub with a spread of 1 – 2 metres. This plant prefers a full sun location and can tolerate drought and moderate frost.

The small light green leaves provide the backdrop for its unique clawed mauve flowers which bloom in Spring.

Pigface (Carpobrotus glaucescens)

This creeping succulent is mostly native to South Africa. However, there are around 6 species that are native to Australia.

It has thick, fleshy leaves that are designed to hold water and bright daisy-like flowers that are bright pink or purple in colour.

This plant is the perfect ground cover in sunny spots as it will spread to cover a large area. It grows naturally in many coastal areas along the east coast and has been helpful in stabilising sand dunes.

Once planted, pigface requires no maintenance except for an occasional prune if it spreads too far.

Westringia ‘Blue Gem’

Westringias are hardy, low-maintenance plants that grow happily in full sun. This particular hybrid has the most spectacular blue-purple flowers that cover the entire plant in spring.

It will grow to a height of 1.5 metres and spread to a width of 1.3 metres. This makes it a lovely rounded shrub that is perfect for more formal landscape plantings.

Westringias prefer well-drained soil and are drought and frost-tolerant. These plants are also quite useful for creating low-growing hedges as they do respond well to pruning.

Native Wisteria (Hardenbergia comptoniana)

Hardenbergia comptoniana is another vigorous native climbing plant. In fact, this variety is considered to be more vigorous than Hardenbergia violacea, featured earlier on our list.

The branches twist around whatever is within reach. This can include the stems of other plants so it can be quite invasive if not kept under control.

This evergreen plant has dark green leaves with pea-like purple blooms that appear from late spring into summer.

Hardenbergia comptoniana can grow in various climates but prefers well-draining soil and full sun to partial shade.

Spreading Flax Lily (Dianella revoluta)

Many people would be familiar with this Dianella’s purple-blue flowers and bright purple berries. Dianella revoluta has firm, strappy green leaves and is excellent for mass planting as a border.

What you may not be aware of is that the berries of this particular species are actually edible and contain tiny, nutty seeds.

This native grass will grow both in full sun and part shade. It can reach a height of 1 metre and a width of 1.5 metres.

It’s also drought and frost-tolerant and attracts bees and birds into your garden.
