Juncus effusus

Common Rush
Juncus effusus
Juncus effusus

A grass-like perennial featuring smooth, upright cylindrical stems that appear absent of leaves; grows in spreading clumps; well suited to aquatic containers and boggy, poorly drained areas; great water garden or pond accent; yellow fall color

Ornamental Features

Common Rush is primarily valued in the garden for its ornamental upright and spreading habit of growth. It features subtle cymes of chartreuse frilly flowers at the ends of the stems from early summer to early fall. Its attractive grassy leaves are green in color. The foliage often turns yellow in fall.

Planting & Growing

Common Rush will grow to be about 3 feet tall at maturity, with a spread of 3 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.
