Reason For Introduction
Reproduces from seed.
Huge numbers of flowers are produced on plants as young as 2 years old. This results in high seed production. Germination is enhanced by fire or mechanical disturbance.
Widely spread as a cultivated plant. Seed dispersed a short distance form parent plant by wind and gravity.
Can tolerate a wide variety of conditions, does particularly well in dry areas.
