Agave americana
 

Perennial succulent with thick grey green sword shaped leaves in rosettes growing to 2m high and often forming clumps that are several metres wide. The leaves have teeth along the margins and a very sharp spine at the tip. Yellow flowers form on a large spike which can rise over 5m in height.

 

HOW IT SPREADS

  • This plant forms thick clusters as the main plant 'suckers' to produce many new plants.
  • Plants that are in dumped garden waste readily take root and colonise natural areas.

Cycas media
Trees and Shrubs
 

This Australian native Cycad looks more like a stout fern. It has a short erect stem and palm like fronds up to 1.5m in length, with stiff green leaflets. This Cycas makes a wonderful accent plant.

Agave attenuata
Succulent Plants
 

This spineless Agave has a thick stem and can reach 1.5m in height. A rosette of thick yet softly textured blue green leaves forms at the crown. Small 'pups' develop to the side of established stems allowing the plant to form thick clumps. This vegetative spread makes them somewhat easier to manage.
