Tasred™- Dianella tasmanica 'TR20' PP18,737

A compact Australian native with bright green and red strap-like leaves. In cooler weather, the red tones radiate from the plant's crown into the leaf margins; spring brings a show of rich blue flowers.

General Description:

• Tight-clumping rhizomatous perennial; slow spread
• Drought tolerant
• Evergreen in normal winters to 25º F (Zones 8-11). Hardy to Zone 7
• Medium growth rate. 1.5 ft. high x 1.5 ft. wide

Position:

• Grows well in filtered sun to partial shade
• Tolerates windy, salt laden positions
• Best suited for free draining soils; avoid depressed areas with saturated soils; slightly acidic.

Planting Density:

• For one gallon pots, plant on 18 to 24 inch centers
• Three gallon pots should be planted on 30 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 leaf spot and possibly crown rot, particularly in areas with high humidity.
• If trimming is required, use a sharp implement and cut to 3 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 increasing planting density and using pre emergent herbicides close to the time of planting, adequate control can be achieved with a minimal investment. For preemergent 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 Baby Bliss is a directed spray of Glyphosate (Roundup). When spot spraying with Glyphosate, ensure drift or overspray does not accidentally contact the Tasred. Do not spot spray on windy days.

Disease and Insect Control:

Susceptible to Colletotrichum fungal leafspot. Tasred is best suited for arid environments but will also thrive in more humid climates as long as it is planted in the right environment. In these areas, plant Tasred in a free draining area (slopes, raised beds, light soils) with no overhead irrigation. If chemical treatment is necessary, a foliar application of a copper-based fungicide and/or chlorothalonyl will control the occurrence of leaf spot. No significant insect problems.
