Introduction
Eremophila is a diverse genus of Australian native plants that includes many excellent ground-covering forms. Ground cover plants are low-growing species that spread across the soil surface, helping suppress weeds, reduce erosion, and cover bare ground. Many gardeners choose eremophila ground cover varieties because they combine drought tolerance, attractive flowers, and minimal maintenance requirements. Prostrate eremophila cultivars are particularly valued in Australian landscapes for their ability to thrive in harsh conditions while providing year-round foliage interest. Whether used on slopes, native garden borders, or coastal landscapes, these plants offer both practical and ornamental benefits.
Quick Summary
- Eremophila is a large genus of Australian native shrubs, several of which grow as low, spreading ground covers ideal for dry and low-maintenance gardens.
- The most widely used ground cover varieties include Eremophila glabra ‘Kalbarri Carpet’, ‘Blue Horizon’, ‘Amber Carpet’, and ‘Roseworthy’.
- Ground cover eremophilas are drought-tolerant, bird-attracting, and suitable for sloped banks, coastal gardens, and native plantings across Australia.
- Most varieties spread 1–3 metres wide while remaining under 50 cm in height, making them effective low-growing weed suppressors.
What Is Eremophila and Why Is It Used as Ground Cover?
Eremophila is a genus of more than 220 species of Australian native plants commonly known as emu bush or emu plants. Many species grow as shrubs, while selected cultivars have naturally prostrate growth habits that make them ideal ground covers.
The Eremophila genus contains more than 220 species native to Australia and belongs to one of the country’s most diverse groups of flowering shrubs. Readers interested in its botanical classification can learn more on Wikipedia’s Eremophila (plant) page.
Ground cover plants spread horizontally rather than vertically. Certain eremophilas are widely used because of their dense foliage, drought hardiness, and ability to cover large areas with minimal maintenance. Eremophila glabra is the species most commonly represented in ground cover cultivars. These plants also provide habitat and food sources for small birds, native insects, and pollinators. Similar to Acacia Baileyana Prostrate, many prostrate eremophila cultivars are selected specifically for their low-growing, spreading habit.
What Is a Low-Growing Ground Cover?
A low-growing ground cover is a plant that typically remains under 50 cm tall while spreading across the soil surface. Its primary purpose is to cover bare ground, reduce weed growth, and improve landscape appearance.
Unlike herbaceous ground covers, many eremophilas are woody shrubs that maintain a spreading habit. Common ground cover examples include prostrate grevilleas, myoporums, scaevolas, and low-growing eremophilas.
How Does Ground Cover Work in the Garden?
Ground cover works by forming a dense layer of foliage that shades the soil surface. This helps suppress weeds, retain moisture, reduce erosion, and create a more finished garden appearance.
Low-growing eremophilas achieve these benefits through their spreading branches and dense foliage, making them particularly useful in difficult landscape areas.
Best Eremophila Ground Cover Varieties in Australia
Several garden-tested cultivars are widely grown across Australia for their reliable performance and attractive appearance.
Eremophila glabra ‘Kalbarri Carpet’
Kalbarri Carpet is one of the most popular prostrate eremophila selections. It produces orange-red tubular flowers and typically reaches 20–30 cm in height while spreading up to 2.5 metres wide.
It performs exceptionally well in hot, dry, and coastal conditions and is frequently used on banks, roadsides, and native garden borders.
Eremophila glabra ‘Blue Horizon’
Blue Horizon is recognised for its blue-grey foliage and lavender-blue flowers. It generally grows 30–50 cm tall with a spread of 1.5–2 metres.
The flowers attract honeyeaters and other nectar-feeding birds. This cultivar is commonly used in coastal gardens and rockeries.
Eremophila glabra ‘Amber Carpet’
Amber Carpet features attractive amber-orange flowers and a dense spreading habit. It remains low-growing while covering substantial ground area.
Compared with Kalbarri Carpet, it offers similar growth characteristics but differs primarily in flower colour and overall visual effect.
