Isotoma fluviatilis, commonly known as Blue Star Creeper, is a semi-evergreen to deciduous perennial herb native to open woodlands and grasslands in Eastern Australia. It typically forms a low-growing mat and can spread quite widely, making it an excellent ground cover. The plant reaches a modest height of 2-5 centimeters and can spread to 30-60 centimeters wide. During the summer months, from November to March, Blue Star Creeper produces a profusion of white to pale blue, five-petalled, star-shaped flowers that create a striking carpet-like effect. The flowers are particularly showy and can add a splash of color to garden beds, rockeries, or when used to fill spaces between paving stones.

Blue Star Creeper is valued for its ability to form dense mats that suppress weeds, making it a low-maintenance option for gardeners. It is also appreciated for its charming flowers and versatility in various garden settings. While it prefers dappled sunlight or part shade, it can tolerate full sun if kept moist. It thrives in moist, well-drained soils and is generally pest and disease-free, although it can be susceptible to root rot if overwatered. This plant is not known for aggressive roots or significant disease problems, making it a reliable choice for cultivation. It is not typically invasive when grown outside its native range but should be monitored to ensure it does not spread beyond desired areas.CC BY-SA 4.0
