Agapanthus (non hybridized)
Agapanthus praecox ssp. orientalis

A clump-forming plant with deep green strappy leaves. Used as a border plant to stabilize low banks and planted by farmers around properties as a fire retardant.

They are known to invade roadsides, bushland and waterways. Agapanthus are grown for their hardiness and striking blue, blue-purple and white flower heads on 1 m stems. Flowers appear in November and December.



  • Often spread by dumping of garden waste into bushland and public space where they may take root and thrive.
  • Each flower head can hold dozens of seeds which are spread by wind, water and soil.

TIP: Removing spent flower heads immediately after flowering can avoid seed spread.

NOTE: There are many hybridized agapanthus available that are infertile or set very little seed. Visit your local garden centre for advice about these superior non invasive hybrids.
