Lomandra confertifolia ‘Olive Green’

olive green matt rush
Neat, fine, olive-green grassy foliage stays in clumps. Fragrant subtle yellow flowers in spring. Good drainage, occasional water once established in the ground. Good in pots. Low to no fertilizer.
height 1–2ft
width 1–2ft
tolerates Cold, Cool Summers, Drought, Deer , Fog, Heat, Pots, Salt, Wind
Low – Moderate
Water this plant infrequently, when the top two inches or so of soil feel dry. Usually this will mean every week or two in dry weather. If you establish this pattern over several years, then you can cut back to watering every four to six weeks in dry weather. Use drippers, emitters, or a slow stream of water so that it doesn’t run off; allow the water to trickle all the way down through the deepest layers of soil. This plant will look more lush if given water every two to four weeks during dry weather once established. In a pot slowly water the entire surface until water comes out of the bottom of your pot.

Growing Notes

Being evergreen, this grassy plant doesn’t need the annual hard pruning of many grasses. It’ll look just fine year round with little work. After many years, when the plants older leaves are being smothered by new ones, a hard pruning in late spring will refresh the clump or you can rake out the older dead leaves.
Maintain the size of lomandra by pulling up the leaves as you would a pony-tail and then cutting them at the desired length. This has little aesthetic affect on the plant, as the leaf tips naturally present with ragged tips.
After blooming, selectively pruning out old flower stalks keeps the clump looking tidy.
Spills handsomely out of pottery, over walls, or down vertical gardens.
More upright and bushy in sun, lower, wider and flatter in shade.

Special Interest

Lomandra was used traditionally by the Aboriginal people of Australia to make nets and mats, thus leading to the common name mat rush.
