Reason For Introduction
Life Cycle Comments
Very fast growing species that thrives in sand dunes. Can have huge impacts in these systems.
Prolific seed is produced in good years, can spread vegetatively if branches touch ground.
Prolific in good years
Dispersed by people as an ornamental shrub. Seed is spread locally by wind, sand and gravity, stem layering is also of some importance.
Copes with coastal spray well.
