Tanika Mat Rush

Lomandra longifolia 'Tanika'

The Story

Plant Bio

Lomandra longifolia is an evergreen Australian perennial native to open forests and coastal heaths across the eastern states. The species forms a dense, strappy tussock of flat, leathery green leaves and produces spiny, straw-coloured flower bracts.

'Tanika' is a compact horticultural selection featuring exceptionally fine, deep green foliage with a graceful, weeping habit. It produces bright golden-yellow flower spikes nestled within the leaves during spring and maintains its rich colour without burning in extreme heat.

Uses & Benefits:

Provides a clean-textured, weeping green foliage accent that maintains its structure and colour year-round.

Delivers extreme drought tolerance and excellent soil stabilisation on slopes and embankments.

Provides protective habitat and cover for lizards and small native fauna, while spring flowers support native bees.

Planting

How to Grow

Plant in a position ranging from full sun to heavy shade, ensuring the soil is well-drained.
Water regularly during the first 8 to 12 weeks to establish a deep root system.
Apply a light application of low-phosphorus native slow-release fertiliser in spring if planting in exceptionally poor soils.
Trim the foliage back conservatively every three to four years, keeping cuts well above the basal growing points.

Pro Tip

Prune the clump back hard to 15 centimetres only once every three to four years to rejuvenate; annual shearing or cutting down into the lower brown woody stems will kill the plant.

Care Guide

Do

Ensure the soil drains well to prevent root rot.
Check for the official PBR label when purchasing to ensure correct genetics.
Leave the plant unpruned for several years at a time.

Don't

Do not plant in chronically wet, stagnant sumps or waterlogged depressions.
Do not shear the foliage back to ground level annually.
Do not cut into the old, brown, leafless woody stems at the base.
