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. 

This information about Lomandra longifolia 'Arctic Tundra' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
