Environmental weeds are often garden escapes and usually spread by birds or garden waste dumped inappropriately. In the past 30 years at least 35% of all plants that have become environmental weeds in Tasmanian were deliberately introduced as garden plants. These include:
- Asparagus fern (also declared)
- Cotoneaster
- Fuchsia
- Agapanthus
- Holly
- Ivy
- Mirror bush
- Foxglove
- Sweet pittosporum
- Perriwinkle
- Poa aquatica/ Glyceria maxima
