Bright green fleshy stems with black bands make this a very striking marginal pond plant! They can form large colonies in wet ground or pond margins so are best contained within baskets to keep them in check, removing any part of the rhizome that starts to grow outside the basket. They will maintain some winter interest in the pond but then should be chopped back in early spring to encourage fresh new growth. Old growth will be cut back for dispatch.
Equisetum comes from equus horse and seta a bristle hence resembling horsetails; Japonica – from Japan
