NUISANCE PLANTS – THE ALIEN INVADERS!!
Plants to avoid
These plants are not
recommended as they are
invasive, non native species that
could rapidly overwhelm your
pond, replacing less vigorous
native plants.
They can also escape into the
wild, causing many problems
and considerable expense to
remove them.
• New Zealand Pigmyweed/
(Crassula helmsii)
• Parrot’s-feather
(Myriophyllum aquaticum)
• Water Fern (Azolla filiculoides)
• Floating Pennywort
(Hydrocotyle ranunculoides ).
Avoid introducing non-native
plants into ponds in the wider
countryside.
Compost any plant materials
removed.
These plants are vigorous non
native species, but will be
providing habitat for your pond
creatures.

(Lagarosiphon major)
• Nuttall’s Pondweed
(Elodea nuttallii)
• Canadian Pondweed

Avoid introducing non-native
