Physical characteristics
Large clumps of broad, silvery leaves up to 1.5m tall.
Flowers and foliage
Broad, flax-like leaves with a silvery sheen. Separate male and female plants. Male plants have dark green, scented flowers and female plants have pale green flowers. Flowers from February to July.
Preferred site
Prefers full sun to partial shade with rich, free-draining soil. Tolerates wind and coastal conditions. Suitable for planting on top of a wall or raised the bed, so they enjoy the good drainage and exposure.
Preparation for planting
Always choose healthy, well-grown plants and plant after autumn rains. Before planting, ensure the root ball is saturated and remove the planter pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball, press in and water once planted. Make sure the plants are watered well until established if planting in a drier period. Plant with some general slow-release fertiliser. After this, apply organic fertiliser, such as blood and bone, at a handful per square metre, in spring as new growth appears. Plant approximately 1m apart.
Maintenance tips
Apply mulch annually to discourage weed growth and help maintain moisture. Keep mulch away from plant stems. Requires no major maintenance except for the removal of unsightly old fronds.
Pests and diseases
Can be susceptible to phytophthora (root rot). Ensure plants have well-draining soil and avoid overwatering.
