Aka horsetail and in the horsetail family, this gorgeous plant is a vigourous spreader so probably best to keep in a pot in your pond and divide often. A living dinosaur plant from the Carboniferous Age. No flowers on this - but you shall be interested in that winter interest...

For the Latin nerds - E. praealtum was decided to be the North American species, but you'll still see E. hyemale (a Eurasian species) as the name (including in the PPL) so we've used it here. Let's fight about it!
