Century Plant


General description

Succulent perennial. Leaves are fleshy, < 2 m long, sharply toothed, dull green or variegated, and formed in basal rosette. Flowers are yellow and borne on flowering stalk in late summer – early autumn. Seed capsules are oblong and contain shiny black seeds. Basal rosette dies after flowering and is replaced by several small lateral rosettes.

What you need to know

To help protect our environment, from 1 September 2021, you:

  • will not be allowed to breed, distribute, release or sell century plant within the Auckland region.
  • will not be allowed to plant century plant within the Auckland region, unless you are transferring an existing plant on your land to another location within the boundaries of the same property.
  • must destroy any century plant on land that you occupy if it has been planted in breach of the above rules and you are directed to do so by an authorised person.

Coastal ecosystems, sand dunes, cliffs, grasslands, open sites, disturbed sites, roadsides, pasture, open canopy forest.

Sets seed. Vegetative spread from rosettes and stem fragments. Seeds and vegetative propagules dispersed by gravity and water. Human-mediated dispersal through dumping of garden waste and deliberate planting.

Forms dense patches in coastal ecosystems, suppressing native vegetation.

Site Management

Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
