Lomandra longifolia 'Arctic Tundra' (Arctic Tundra Mat Rush) - An attractive upright evergreen grass-like perennial that grows to 3 feet tall by 3 feet wide with medium narrow dark green leaves. The leaves are at first erect towards the center of the plant and the arch over gracefully at the edges. As with other Lomandra, the leaf tips are curiously cut as though with pinking shears at the tips but are so narrow on this cultivar that this aspect is hardly noticeable.
Based on our experience with other lomandra varieties, we recommend planting this cultivar in full coastal sun to bright shade in a fairly well-drained soil. It should prove moderately drought tolerant once established, but can also tolerate regular irrigation and should prove hardy to just below 20° F and be useful in USDA Zones 8 and above. One can cut back clumps every few years if needed to clean up and renew foliage.
This plant is a non-variegated sport removed from our crops of Lomandra 'Arctic Frost', which itself was a variegated sport of Lomandra longifolia Nyalla ['LM400']. While we have found some sports of 'Arctic Frost' that appear identical to the Nyalla cultivar, some have deeper green shorted and broader leaves, and it is these that we have separated and named Lomandra 'Arctic Tundra'.
The name Lomandra comes from the Greek words 'loma' meaning "margin" and 'andros' meaning "male" and is in reference to a circular margin on the anthers. The specific epithet 'longifolia' means "long leaves". The genus Lomandra has long been placed in the past with the Australian Grass Trees in the Xanthorrhoaceae or related Dasypogonaceae and then more recently in its own family, the Lomandraceae, or combined with the Cordyline into the Laxmanniaceae. Current treatment is to put it in the subfamily Lomandroideae in the Asparagaceae.
