Pros and cons

  • Striking 'meadow' carpet in the foreground
  • Propagates via runners along the substrate
  • High decorative value
  • Dense carpeting needs CO₂ and bright light
  • Without CO₂, grows sparse
  • Sensitive to nitrates above 30 mg/L

Description

A dwarf form of needle spikerush — only 3–6 cm tall, the perfect foreground. Forms a dense carpet in 2–3 months.

Care

Nutrient substrate, bright light; CO₂ speeds up carpet formation.
