Heath Rush (Juncus squarrosus) belongs to the Juncaceae family within the Juncus genus. Heath Rush is native to Iceland, Europe, and Morocco, and introduced to Greenland, Svalbard, Tasmania, New Zealand, and the US state of Wisconsin. Heath Rush is also known as Field Rush.

Heath Rush displays a grass-like clumping growth habit, reaching up to 1.5 ft tall with a spread of approximately 0.5 ft. Heath Rush produces inconspicuous brown or green flowers in terminal clusters.

Leaf size: approximately 12 inches.

Juncus squarrosus requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Heath Rush thrives in full sun to part shade.

Juncus squarrosus grows best at temperatures of 50–80°F. Heath Rush prefers humidity levels of 40–70%.

Moist, well-draining soil rich in organic matter. Good drainage is essential for Heath Rush to prevent waterlogging, which leads to root rot and fungal issues.

Divide and repot every 2-3 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
