Field horsetail is also known as marestail. Once established, it has roots that extend to 2m deep, and spreads by means of creeping rhizomes. The plant produces light-brown stems in late spring, topped with cone-like structures, and these are followed by light-green shoots up to 60cm in height. The plant spreads among cultivated plants, making for a messy appearance and competing for water and nutrients.
A deep-rooted, herbaceous weed, with tough, light-brown or green shoots that resemble pine needles. It dies back completely in winter.
