Not common.  In damp and often shady ground that is not too acid

Stems 8-12 mm across.  Plant can be up to 2 metres tall but seems to be always much lower in our area.

ID: Sheaths normally have over 20 teeth and plant is profusely and regularly branched along its entire length

Other features: Sterile stems whitish or pale green.  Fertile stems (brown, with cones) do not have branches or turn green but die down in early summer, and have sheaths with 20-30 teeth; no other Horsetail normally has brown fertile stems with more than 20 teeth.
