BioRhythm is a multi-sensory landscape and immersive public art installation: a living, adaptable sculpture that transforms biofeedback from endemic plants and the surrounding urban environment into soothing explosions of colour and a constantly evolving light and sound show.
By blurring the lines between biology, technology and place, BioRhythm fosters learning and connection while igniting curiosity and discovery within the public realm. As people move through the installation they are invited to explore nature's intrinsic role in urban environments, and to deepen their sense of place through QR-linked educational material about the plants.

Edition 01
Testing
Grounds





As the sun goes down the sculpture wakes up. Sensors read the plants and the city around them, and the columns answer in colour and sound.






Edition 02
Grattan
Gardens

For three months the sculpture transformed the public square at the junction of Greville Street and Grattan Gardens, planted with species endemic to the area.
The second edition was planted with indigenous species selected with the help of Rewilding Stonnington. Each plant carried a QR code linking to information about its habitat, its role in the local ecosystem and, for some, its traditional uses.
The program opened with Lights On on 17 April, followed by a Rewilding Tour on 22 April: a walk that began at BioRhythm and continued on foot around Prahran, looking at Rewilding Stonnington's recent projects and at how communities can foster biodiversity and reconnect with traditional knowledge in their own neighbourhoods.
The square was open to the public, wheelchair accessible, and the installation ran daily from 7am to 10pm.

Endemic plants used in BioRhythm
The
Plants
The 2024 edition was planted with species indigenous to the area. Open each one to read about it.
Creeping Monkey FlowerMimulus repens
A herbaceous creeping perennial. This low-growing plant forms dense mats of creeping stems that root at the nodes, allowing it to spread and form colonies. It flowers mainly in spring and autumn, and its mauve flowers can resemble a monkey's face. The flowers attract pollinators such as bees and butterflies. Grows predominantly on the margins of lakes, swamps, rivers and grassy wetlands.
Lemon BeautyCalocephalus citreus
A small perennial herb of slender branches, typically found in coastal habitats including sand dunes, heathlands and rocky outcrops. It thrives in well-drained soils and is adapted to harsh coastal conditions, including salt spray and strong winds. It is known for its striking silver-grey foliage, densely packed into a compact, rounded shape, with small, narrow, woolly leaves. Inconspicuous yellow flowers may appear in summer.
Cut Leaf DaisyBrachyscome multifida
A perennial herb found in the grassy understoreys of woodlands and open forests, and a member of the Asteraceae family. It grows best in full sun but tolerates part shade, and grows on a range of soils from heavy clays to light sandy loams. Features pale purple daisy flowers.
Small-leaved ClematisClematis microphylla
A woody climbing shrub or trailer ascending to 3–5 m, often scrambling over other vegetation or rocky outcrops. Leaves divide repeatedly into three leaflets. Male and female flowers grow on different plants; the flowers have four oblong, creamy-white, petal-like sepals but no true petals, and are star-shaped and fragrant. Its fruits are feathery and persistent, and small birds like to nest in them. Its roots can be eaten when toasted and were made into dough by Traditional Owners. Left to grow it will cover neighbouring plants without damaging its host, and a single plant can live for several decades.
Creeping BoobiallaMyoporum parvifolium
A low-growing shrub with small, glossy green, slightly succulent leaves. In spring and summer it produces small, white, star-shaped, fragrant flowers that attract bees and butterflies. Its creeping habit forms a dense mat that spreads horizontally, and it can be trained to cascade over walls. Tolerant of salt and wind, it is often used to stabilise soil on slopes, suppress weeds and control erosion.
Running PostmanKennedia prostrata
A common ground cover that forms a dense trailing or matting shrub. Its leaves are divided into three crinkly, roundish blue-green leaflets with notched tips. Over spring it produces striking red pea flowers on long stalks, which turn into brown pods over summer containing glossy black seeds. Running Postman is food for caterpillars and nectar for butterflies.
Velvet TussockPoa morrisii
A tufted or shortly rhizomatous perennial forming a dense bluish-grey tussock of flat, velvety leaves. From October to December it carries an open, pyramidal flowerhead that is green or purplish. It often forms mounds, grows well under trees, and suits difficult dry, shady spots.
Vanilla LilyArthropodium milleflorum
A perennial herb with long, slender leaves rising from a central base and delicate pale flowers with a sweet, vanilla-like fragrance, borne in clusters on long stems in late spring and early summer. The flowers attract bees and butterflies. Once established, its fleshy tubers are edible and can be cooked much like potatoes.
Wonga Wonga VinePandorea pandorana
A flowering, evergreen woody vine in the Bignoniaceae family that climbs by tendrils and can grow several metres long. Its trumpet-shaped flowers are white to pale pink and sweetly fragrant, appearing in clusters in the warmer months and attracting bees and butterflies. The dense foliage of an established vine provides habitat for small birds and other wildlife.
Wallaby GrassRytidosperma racemosum
Found in grasslands, woodlands, open forests and coastal areas, on soils from sand to clay. This perennial grass grows in tufts with slender, wiry stems up to a metre tall and fine, narrow leaves. In spring and early summer it produces delicate flower spikes in open clusters. It provides food and habitat for insects, birds and small mammals: the tufts offer shelter and nesting sites and the seeds are an important food source. Wallaby Grass can also be used for weaving.
Blue Tussock GrassPoa sieberiana
A low-growing perennial tussock grass of grasslands, woodlands, open forests and alpine areas, preferring well-drained sandy or loamy soils. It grows in dense clumps with slender upright stems up to a metre tall and narrow, bluish- to grey-green leaves. In spring and summer it produces delicate flower spikes in loose clusters. The tussocks offer shelter and nesting sites, and the seeds are an important food source for many species.
Australian IndigoIndigofera australis
A leguminous shrub whose genus name is Neo-Latin for "bearing indigo" — the purple dye originally obtained from some Indigofera species. Found in forests, woodlands, heathlands and coastal areas, it has delicate pinnate leaves that give it a fern-like appearance, and small pea-like flowers, usually pink or purple, in elongated clusters. The plant can be used as a dye for colouring fabric.
Cushion BushLeucophyta brownii
A bushy shrub with silvery-white foliage, found in coastal heathlands, sand dunes and limestone cliffs. Well adapted to salt spray and strong winds, it has a distinctive rounded form and small, cylindrical, silvery-grey leaves covered in fine hairs that reduce moisture loss and protect against salt. The dense foliage provides shelter and nesting sites for small birds and other wildlife.
Ruby SaltbushEnchylaena tomentosa
A low-growing, semi-woody sub-shrub of the arid and semi-arid regions of Australia, including coastal dunes, inland plains and rocky outcrops. Its striking red berries contrast with small, oval, silver-grey leaves covered in fine hairs. Small greenish-yellow flowers appear in spring to early summer, followed by the berries, which can be eaten and used as a dye. The berries are an important food source for native birds such as finches and honeyeaters.
Prostrate GoodeniaGoodenia ovata (prostrate form)
A low ground cover — the prostrate form of Hop Goodenia. It has green, ovate leaves with toothed margins and produces yellow flowers from late spring. Wind- and salt-tolerant, it is very useful as ground cover in coastal gardens.
Happy WandererHardenbergia violacea
Also called Purple Coral Pea, a vigorous twining vine in the pea family, Fabaceae, typically reaching 2–3 m. Its compound leaves have three leaflets, and clusters of pea-shaped flowers, usually purple or violet, bloom from late winter to early spring. It can be grown as a ground cover, climber or trailing plant.
Common EverlastingChrysocephalum apiculatum
Also known as Yellow Buttons. A low-growing perennial herb, typically 15–30 cm tall, with narrow, woolly, grey-green leaves. Small yellow button-like flower heads bloom from spring through summer and sometimes into autumn, attracting bees and butterflies. Often used as a ground cover, border plant or in rock gardens.
