Quick facts

About Common rush

Juncus usitatus, commonly known as common rush, is a perennial plant native to Australia, forming dense clumps of bright green, cylindrical, upright stems. It's an excellent choice for ponds, wetlands, or as an accent plant in naturalistic or aquatic gardens, providing interesting vertical texture. Its slender appearance and ability to thrive in wet conditions make it ideal for areas where other plants would not tolerate.

Native range

Australia and New Zealand

Care tips

It prefers full sun to partial shade and consistently moist, even waterlogged, soils, making it perfect for water's edge. Watering should be frequent and abundant, ensuring the substrate never dries out completely; in fact, it tolerates and prefers standing water. Use a substrate rich in organic matter with good moisture retention, such as an aquatic plant mix or heavy garden soil. A common mistake is trying to grow it in dry soils or with sporadic watering, which will lead to its decline.
