Agave angustifolia is grown for its striking shape and ability to withstand periods of little or no water.
It is very popular in small courtyards and outdoor pots.
The thick leaves have serrated edges in a rosette formation.
It may take 10 years to flower but when it does the flower is quite spectacular.
The flower inflorescence appears at the end of tall stalk (up to 2.5m).
The plant develops suckers from the base and bulbils from along the stalk that fall off and and grow into new plants.
This plant is now considered a weed in Queensland and NW New South Wales.
It is ranked in the top 200 most invasive plant species in SE Queensland. (ref: Queensland Government Weeds of Australia)
