The Story
Plant Bio
Equisetum hyemale, or Scouring Rush, is a non-flowering, evergreen perennial and fern ally. It features hollow, jointed, bamboo-like stems that are rough-textured due to silica content. It spreads aggressively via creeping rhizomes to form dense colonies. Valued for its strong vertical, architectural form in modern and minimalist landscape designs. Its aggressive, spreading nature requires containment, often by planting in submerged containers. The silica-rich stems were historically used for scouring and polishing.
