What is the common name for Juncus?
Juncus is a genus of monocotyledonous flowering plants, commonly known as rushes. Juncus provide habitat for wildlife and help keep our water clean. According to the USDA, the rhizomes of Common Rush (Juncus effusus) form a matrix for many beneficial bacteria, making this plant an excellent addition for wastewater treatment.Juncus effusus requires moderate summer watering (irrigation), generally 1 – 4 times per month depending on the absorption rate and water retention capacity of the soil. Salt rush plants may need to have their roots in moist or wet soils.
Does Juncus spread?
Plants will spread in the landscape by rhizomes and by self-seeding. Rhizomatous spread may be controlled, if desired, by growing this plant in large containers sunk in the ground. Foliage remains evergreen in warm winter climates or when grown indoors as a houseplant. It can spread aggressively by rhizomes or self-seeding and clumps can easily be divided in the spring and replanted directly into the soil. The stems may appear to be coarse and stiff, but they are soft to the touch.They prefer full sun but can tolerate some shade. They require consistently moist soil and they grow well in pots and as houseplants. Spreading and propagation are by division of the rhizomes and self-seeding which can be difficult to manage.
