Equisetum hyemale

Scouring rush or horsetail rush is a bold, upright, evergreen perennial with jointed stems and a vigorous growth habit. Throughout the growing season it maintains a striking architectural presence with deep green, bamboo-like stems accented by dark nodes. Rather than showy flowers it produces subtle, cone-like spore structures at the stem tips that add quiet botanical interest. This ancient plant provides shelter for amphibians, insects, and other small wildlife, helps stabilize soil while slowing and filtering runoff. Novelty and beauty aside, it can be an aggressive spreader and may be best planted in a container, particularly in small urban or sub-urban lots.

Plant type/canopy layer: evergreen, perennial, herbaceous plant
Size at maturity: 24-48" tall, thin stalks spread quickly and laterally by rhizome
Light requirements: full sun, part sun/part shade, full shade
Moisture requirements: moist to wet soil
Bloom time: n/a
Growth rate/ease: medium to fast growth rate, easy to grow
Wildlife support: stems provide critical habitat, offering dense cover for wetland birds, amphibians, and reptiles, while serving as a key perching spot for dragonflies. While high in silica and generally unpalatable to deer, it is eaten by animals like caribou, moose, and bear. It's also a beneficial insect magnet, providing habitat for aquatic invertebrates and food for sawflies, weevils and beetles. As they "die" and decompose, they contribute to the detritus that forms the base of the food chain for other aquatic life.
Native habitat/range: primarily found in wetlands and riparian zones, moist forests, forest edges, swamps and fens across an impressively widespread native range spanning temperate regions in most of Canada, the contiguous United States, Alaska, and throughout Eurasia to Japan. Portland Plant List - yes.
Special features & uses: deer resistant; erosion control; tall groundcover; ethnobotanically, the rough bristles have been used to scour or clean pots, used as sandpaper, as well as to shape the reeds of reed instruments such as clarinets or saxophones. Boiled and dried it is used as traditional polishing material like fine grit sandpaper in Japan. Final anecdote - this species can indicate an underground seep or spring, even when it’s otherwise unnoticeable; landscape uses include container and vertical gardening, ethnobotanical gardens, water features and ponds

Gardening with Scouring Rush: This prehistoric-looking species thrives in full sun to part shade and prefers consistently moist to wet soils, tolerating seasonal flooding and standing water with ease. In a habitat garden, it can be used as a bold vertical accent along pond edges, in rain gardens, or as a living screen where its strong form contrasts beautifully with softer wetland plants. To keep it thriving and well behaved, plant it where spreading is acceptable or contain it with barriers. Traditional gardening advice would encourage cutting back damaged or old stems in early spring to encourage fresh growth. Though it’s generally better for habitat to leave old stems to decompose in place. Do what works for you. :)
