Juncus acuminatus
Taper-tip rush is a lesser-known raingarden superstar that will add year-round interest and structure to your garden. Its soft, vibrant green foliage is evergreen, forming a hardy, low-maintenance groundcover with exceptional habitat benefits in sunny moist to wet areas. The flower cluster is an open array of up to 20 teensy-weensy green to reddish-brown inflorescences; a natural firework display for all the lovely, industrious ants that call a habitat garden home.
