Juncus effusus #1 (Soft Rush)

Soft Rush adds an interesting vertical and spikey textural element to a pond-side garden. This wetland plant enjoys sunny, soggy areas and can grow into 4′ tall clumps, providing excellent cover for marsh wildlife. The dark green, leafless stems of this plant remain evergreen, though the tips do die back a bit in winter, adding attractive brown and grey streaks to the planting. The small flower clusters protrude from the tip of the photosynthetic stems and dangle on the plant until they fall off or blow away to establish a new clump elsewhere.
