King Alfred® Dianella caerulea ‘JOHN316’ PBR

• Best erosion control plant – strengthens the soil by 752%
• Dense compact blue green foliage
• Great rain garden plant

Description: King Alfred® Dianella is the best erosion control plant available, strengthening the soil by 752% (2007 Paananen, Layt; Study).

With very short canes, and sometimes none at all, King Alfred® Dianella is a tidy plant with purple and yellow flowers that reach 1m high from September – March.

Size: 70cm high x 70cm wide.

Planting Density: 2–4 plants per m², 1.5–2 plants per linear metre.

Uses: Mass planting or specimen planting

Species: Dianella caerulea

Position: Full sun to moderate shade. Tolerates humidity, cold and is moderately drought tolerant. King Alfred® Dianella suits a wide variety of soils. Avoid very poor soils.

Care: Water as required for 8-13 weeks until established. Plant in a well mulched garden (chunky mulch is recommended). Ensure crown or base of plant is not below soil or mulch level.

If required use slow release fertiliser in spring. Every 1-2 years cut back 15cm above the ground (will look better with pruning every year, this depends on your requirements). 

As this is a fast growing Dianella, it will require cutting back more often, but responds very well to being cut back.

If it is not cut back every 2 years (minimum), it can become overgrown, and be short lived. With regular pruning it is a reliable, long lived, tidy Dianella.
