Nyalla™ - Lomandra longifolia 'LM400' PP15,583

Similar in form to Breeze, Nyalla is a slightly larger, fine-leafed Lomandra longifolia, with a distinct blue-green foliage and multiple cream-colored flower heads in the spring. Nyalla is well suited for arid environments.

Name: Nyalla
Plant Species: Lomandra longifolia

General Description:

  • Clumping perennial
  • Extremely drought and heat (120+º F) tolerant
  • Evergreen in normal winters to 25º F (Zones 8-11). Cold hardy to Zone 7
  • Medium growth rate. 3 ft. high x 3 ft. wide


  • Grows well in full sun and moderate to heavy shaded positions
  • Tolerates windy, salt laden positions
  • Best suited for free draining, lightly acidic soils. It is best to avoid depressed areas that hold water

Planting Density:

  • For quart or one gallon pots, plant on 30 inch centers
  • Three gallon plants should be specified on 36 inch centers

Plant Care:

  • Do not bury the crown of the plant when planting
  • Water as required to keep the plant healthy for the first 8 to 16 weeks; Do not over water; saturated soils can lead to
    crown rot, particularly in areas with high humidity.
  • If trimming is required, use a sharp implement and cut to 6 in. above the ground. Avoid trimming in drought conditions,
    or in the middle of summer.
  • Fertilize in spring and fall using a slow release fertilizer with a 3:1:3 blend ratio plus micronutrients (Iron)

Weed control:

As with all weed control, a proactive approach is usually the most effective. By using pre-emergent herbicides close to the time of planting, adequate control can be achieved with minimal labor investment. For pre-emergent weed control, use Ronstar or Rout at the labeled rate. If post emergent control is needed, Fusilade can be used to selectively remove grass weeds. At this time, the only known method for removing broadleaf weeds (post emergence) from Nyalla is a directed spray of Glyphosate (Roundup). When spot spraying with Glyphosate, ensure drift or overspray does not accidentally contact the plant. Do not spot spray on windy days.

Disease and Insect Control:

Proper horticulture practice teaches us to “use the right plant for the application.” The correct application for Nyalla is “xeric” landscapes. In areas that receive excessive rainfall and have extended periods of high humidity Nyalla is prone to Phytopthora rot. Use Nyalla in minimal or no irrigation landscapes with well drained soils for best results. A soil drench with a thiophynate-methyl/ mefonoxam/ phosphorous acid based product(s), will reduce mortality rates. No significant insect problems.
