About
Dichondra repens, commonly known as kidney weed, Mercury Bay weed, tom thumb, or yilibili in the Dharawal language, is a species of flowering plant in the family Convolvulaceae and is native to Australia, New Zealand, and the Indian Ocean islands, Mauritius, Réunion and Rodrigues. It is a perennial, herb with kidney-shaped to round leaves and small, greenish-yellow, star-shaped flowers.
How to grow it
This species is cultivated as an ornamental plant, and can be used as a lawn substitute or groundcover in gardens.
Safety
D. repens uses acylsugars as a chemical defence. Among these are acylated resin glycosides which synergize with antibiotics to reverse bacterial multidrug resistance (MDR).
Where it grows
Kidney weed is widespread in all Australian States and New Zealand, and occurs on Mauritius, Réunion and Rodrigues in the Indian Ocean. It grows in forest, woodland and grassland on clay or clay-based soils that are medium to high in nutrients, and is a weed of lawns. Associated species in New South Wales are river peppermint (Eucalyptus elata), thin-leaved stringybark (E. eugenioides), woollybutt (E. longifolia) and snow-in-summer (Melaleuca linariifolia).
