Dwarf horsetail or Dwarf scouring rush. The thin, wiry stems of this dwarf cousin to the well-known horsetail, reach 6-8” tall and form dense mats of segmented, dark green stalks. Rush-like, with a unique architectural quality and small club-shaped fruits, this is a good choice for small containers. Rhizomatous by nature, it may need some restraint to keep from becoming invasive, particularly in wet or boggy sites; plants will not spread where water is withheld. Tolerant of windy coastal conditions, moderate shade, and cold, as well as full sun and heat, the dwarf horsetail only needs constant moisture to look its best, and in fact grows well in shallow water. In cool weather plants take on a slight burgundy hue. Hardy to below 0F. Eurasia, Greenland, North America.
