Equisetum arvense Field Horsetail CCC D N
This shows both the reproductive cone and the mature leaves of the plant. In E. arvense the cone appears before the leaves. This is a garden weed but I wish that we didn't have it here - it is one of the most difficult plants to remove as the roots appear to go down to somewhere near the magma layer.
E. arvense is found throughout the British Isles and Ireland.
