The Orange sedge is well named. It is a dramatic clumping perennial with green to shocking orange foliage color, fine texture and a distinctive mounding habit. Mature plants can reach 18 in. high.

This species is native to both the North and South Island of New Zealand and is good for cascading over walls and in containers to help keep its foliage off the ground. The orange color is enhanced when planted in sunny exposures, but avoid hot afternoon sun conditions during summer. It is hardy to cold and does best with regular water throughout the year.

Water Needs

The Orange sedge is well adapted to the Inland Empire in full sun with moderate water throughout the year. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several winter months marked by an asterisk (*) when rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; higher amounts of water within this range will help this sedge maintain good foliage character year around.
