Equisetum scirpoides

Dwarf version of the common horsetail reaching only 6-10″ tall and spreading to form a matted groundcover to 3-4 ft wide. Thin, dark green stems have black banding at the nodes — a nice texture. Happy in sun or shade as long as there is water around. Can be submerged up to 2″. Like its larger cousins, a vigorous spreader, so best restrained in containers. Frost hardy to -40F, USDA zone 4.
