Best uses

These plants offer striking contrast when creatively mixed with shrubs, ground covers, grasses and ferns. They are great for small gardens and can also be used as container plants.

Physical characteristics

A clump-forming, evergreen perennial that grows to a height of 60cm and width of 60cm.

Flowers and foliage

Bold strap-like green leaves, around 60cm in length. Spikes of white flowers appear in late spring to early summer.

Preferred site

These plants prefer partial to full sun and tolerate dry and coastal conditions. They are susceptible to frost damage.

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.

Planting too closely leads to spindly growth, poor flowering and eventual plant decline. In a well-planned border, the plants in flower should just touch each other to create a full effect without overcrowding. Plant approximately 50cm apart. Slug bait may be needed as they are very susceptible to damage.

Maintenance tips

Apply mulch annually to discourage weed growth and help maintain moisture. Fertilise in spring with a balanced fertiliser, such as blood and bone, at a handful per square metre. Prune any old flowers after flowering.

Pests and diseases

Susceptible to slug and snail damage.
