Type of weed: Herbaceous weed
An erect perennial herb with ribbed or grooved hollow stems annually to 60cm high. Stems are jointed, rather succulent with a long spore-producing cone at the tip. In spring they produce small green branchlets in whorls, (around the stem) below the cup-shaped sheaths.
Leaves are usually green but often brown on the lower stem. This plant dies back during winter.
Horsetail does not produce flowers or seed, but does produce fertile spores.
Don’t confuse with…
Horsetail can be confused with the native Clubmoss (Lycopodium lateralis).
Spreads commonly by road-making and moving of soils out of infested areas carrying rhizome or tuber (root) fragments over long distances to start new colonies. Also spreads as a result of spores dispersed by wind and water.
Impact on bushland
Horsetails are mostly found in wet areas such as the banks and edges of swamps and creeks. They can form dense clumps and produce inhibitory substances that suppress the growth of native plants.
