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.



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

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.
