This species is often traded due
to its bright, attractive yellow
flowers. It is an extremely
invasive perennial herb that
has the ability to entirely choke
slow moving or still water
bodies. It produces daughter
plants at the ends of stolons
that can become detached
and float away to establish
elsewhere. It is a major weed
in SE QLD and in parts of
NSW and its planting in any
garden or water body should
be strongly avoided due to its
invasiveness and adaptability.
This plant has undergone a
weed risk assessment and
has been recommended for a
national ban.
