What You'll Learn
Wreath flower's scientific name
The wreath flower, scientifically known as Lechenaultia macrantha, is a species of flowering plant in the Goodeniaceae family. It is native to inland areas of southwestern Western Australia, specifically in the Avon Wheatbelt, Geraldton Sandplains, Murchison, and Yalgoo regions. The specific epithet "macrantha" means "large-flowered".
Lechenaultia macrantha is a low-lying, wreath-like herb or subshrub with narrow, fleshy leaves. The flowers are arranged in compact groups, with yellow petals and deep pink or red wings. They typically grow to a height of up to 15 cm and a diameter of about 1 meter. This wreath flower is known for its unusual circular shape and its mysterious growth patterns, as the colours vary each year from white to pink, orange, and red.
The wreath flower typically blooms between August and October, depending on seasonal rainfall and climatic conditions. It thrives in disturbed areas such as road verges, gravel pits, and recently burnt areas. While it is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, it is not commonly found in cultivation and can be challenging to maintain for more than a couple of years.
Another variety of wreath flower is the Bridal Wreath Spiraea, with the scientific name Spiraea prunifolia. It is native to China, Taiwan, Korea, and Japan and is a member of the Rosaceae or rose family. The genus name "Spiraea" is derived from the Greek word "speira," meaning "wreath," reflecting the showy, wreath-like appearance of its flowers.

It is known for its distinctive wreath-like shape and vibrant colours. The wreath flower typically grows in open areas with sandy or gravelly soil. It is particularly associated with regions such as Tallering Station, Coorow, Kalbarri, Boolardy Station, the Avon Wheatbelt, Geraldton Sandplains, Murchison, and Yalgoo. These areas fall within the biogeographic regions of inland south-western Western Australia.
The wreath flower often thrives in disturbed areas and can be found along road verges, gravel pits, or recently burnt areas. It is known to grow well after bushfires, making it a common sight in certain regions of Western Australia. The Mullewa District, several hours' drive northeast of Perth, is one such area where the wreath flower is a star attraction among wildflowers.
The specific epithet "macrantha" translates to "large-flowered". The wreath flower typically blooms between August and October, although this timing is influenced by seasonal rainfall and climatic events. The colours of the wreath flower can vary from year to year, ranging from white to pink, orange, and red. This variability adds to the mystery and allure of this unique wildflower.
The wreath flower is just one of the many wildflowers that contribute to Western Australia's legendary floral diversity. This biodiversity hotspot boasts over 12,000 different varieties of wildflowers, many of which are found nowhere else in the world. The Wheatbelt, renowned for its carpets of everlastings, is a popular destination for wildflower enthusiasts during the blooming season.
Overall, the wreath flower is a striking symbol of Western Australia's natural beauty and ecological significance. Its growth habits and distribution contribute to the region's vibrant wildflower landscapes, attracting visitors from far and wide.

When it blooms
Lechenaultia macrantha, commonly known as the wreath flower, is a species of flowering plant native to inland areas of southwestern Western Australia. It is a low-lying, wreath-like herb or subshrub with narrow, fleshy leaves and unique yellow and deep pink or red petals.
The wreath flower typically blooms between August and October, marking the beginning of Western Australia's wildflower season. However, the specific timing of its bloom is influenced by seasonal rainfall and other climatic factors. The wreath flower is known for its mysterious growth patterns, with colours varying annually from white to pink, orange, and red. This variability adds to the allure of the wreath flower, as its appearance is never quite predictable.
The wreath flower thrives in disturbed areas, often appearing on road verges, gravel pits, or recently burnt land. It is particularly associated with the Mullewa District, where it is the star attraction among the region's wildflowers. The wreath flower's ability to grow in such environments is advantageous, allowing it to quickly colonise open spaces and create a vibrant display.
The plant typically grows to a height of up to 15 cm and a diameter of about 1 metre. Its flowers are arranged in compact groups, with sepals measuring 20.5-33 mm and petals ranging from 25-35 mm. The upper petal lobes stand erect, while the lower lobes spread outward, contributing to the wreath-like appearance.
While the wreath flower is not considered threatened, it is challenging to cultivate and maintain in gardens. Its wild nature makes it best suited to its natural habitat, where it can spread freely and create the stunning displays for which it is known.

Why it grows there
Lechenaultia macrantha, commonly known as wreath leschenaultia or wreath flower, is a species of flowering plant in the Goodeniaceae family. It is native to inland areas of south-western Western Australia.
Wreath flower is a low-lying, wreath-like herb or subshrub with narrow, fleshy leaves. Its petals are yellow with deep pink or red wings. It grows in open areas with sandy or gravelly soil and is commonly found on road verges, gravel pits, or disturbed areas that have been recently burnt.
The growth patterns of the wreath flower are considered mysterious, and the reasons behind their specific growth locations are not well understood. However, some factors may contribute to their preferred growth conditions and unique form:
- Climate and Geography: The wreath flower is endemic to inland areas of south-western Western Australia, which experiences a specific climate and geographical conditions. The region's climate may influence the growth of the flower, with hot and windy conditions and low rainfall potentially shaping its low and round growth habit.
- Disturbed Areas: Wreath flowers thrive in disturbed areas, often appearing on road verges, gravel pits, or recently burnt sites. This adaptability to disturbed habitats may be a factor in their growth location preferences.
- Soil Type: They grow well in sandy or gravelly soils, which are typical of the regions where they are found.
- Pollination: While the specific pollinators of the wreath flower are not mentioned, the presence of native bees, beetles, and flies in the areas where they grow suggests that these insects may play a role in their pollination.
- Evolutionary Advantages: The unique wreath-like shape of the flower may offer evolutionary advantages, possibly related to heat and water conservation, given the low-rainfall regions where they grow.
The growth patterns and colour variations of the wreath flower remain intriguing aspects of this wildflower, adding to its appeal and mystery.

How to grow it
Wreath Leschenaultia, or Lechenaultia macrantha, is a species of flowering plant native to inland areas of southwestern Western Australia. It is characterised by its low-lying, wreath-like form, narrow fleshy leaves, and yellow petals with deep pink or red wings.
Climate and Soil:
Wreath Leschenaultia is adapted to warm temperate, semi-arid, and arid climates. It thrives in sandy or gravelly soil, particularly in well-drained, dry conditions. While it can tolerate some frost, it struggles in high summer humidity.
Sunlight:
This plant prefers full sun to light shade, requiring around 6 hours of sunlight per day for a full bloom.
Propagation:
Propagation through seeds is recommended, as propagating by cutting can be challenging. When planting seeds, ensure the soil is well-drained, lime-rich, and preferably sandy. Wreath Leschenaultia is sensitive to phosphates, so use low-phosphate fertilisers designed for Australian native plants sparingly.
Pruning:
Occasional pruning is recommended to control the shape and remove spent blooms. However, be cautious as wreath Leschenaultia does not respond well to light or aggressive pruning, which can affect flower production and damage branches. Always use sterilised gardening shears to prevent the spread of pests and diseases.
Pot or Hanging Basket:
Consider growing Wreath Leschenaultia in a small to medium-sized pot or hanging basket, particularly if you want to showcase its trailing growth habit. This can add colour and texture to your patio, pool, or flower bed borders.
Please note that this plant has strong, invasive roots, so avoid planting it near pipes or main connections. Additionally, it is not widely cultivated and can be challenging to maintain for more than a couple of years.
