Name: Field horsetail
( bottle-brush, horse pipes, mare ) Latin name: Equisetum arvense L.
Field horsetail is part of the ancient genus Equisetum, which was the dominant plant group during the Carboniferous age more than 230 million years ago.
It is an invasive, deep-rooted perennial weed that will spread quickly to form a dense carpet of foliage, crowding out less vigorous plants in beds and borders.
The roots can penetrate very deep into soils, roots have been seen to grow down to two metres in depth. The plant produces numerous rhizomic growths, which enable the plant to colonise areas quickly.
Horsetail is an invasive, deep-rooted weed with fast-growing rhizomes (underground stems) that quickly send up dense stands of foliage.
