Dwarf Horsetail Rush
Dwarf horsetail rush
A 10 cm length of rhizome has been shown to produce a total of 64 m of rhizome in 1 year. It has been estimated that horsetail has the potential to infest an area of 1 hectare within 6 years of introduction. Tubers germinate when separated from the rhizome system and can remain viable for long periods in soil.
