Umbrella Plant, Cyperus involucratus, Galingale
|Water-loving, these tall, striking perennials grow best near pools or partly submerged in shallow water. In pots outdoors, keep soil moist. In containers indoors, grow in water 2 to 6 inches deep. Palm-like leaves atop bare stems are green to reddish-brown. Use in fresh or dried arrangements. Full sun or shade, but will not tolerate frost. Start by division or seeds sown in spring or early autumn. Remove dead or broken stems and leaves.
Its long, pointed leaves look like umbrella spokes. Invasive in pools. Yellowish spring blooms. Smaller Nanus, or Gracilis, is better outdoors. Variegatus has white-striped leaves and stems.
