Overview

Pilea nummulariifolia is one of about 700 species in Pilea, the largest genus in the nettle family Urticaceae. A creeping Caribbean and South American species with small round mid-green leaves on thin stems, used as a ground-cover under taller plants and in terrarium settings. Despite the family connection, Pilea lack the stinging hairs of Urtica.

Care Priorities

  • Bright filtered light keeps growth compact; deep shade leaves leggy.
  • Water when the top 2 cm of mix is dry.
  • Average humidity (40 to 60 percent) is enough.
  • Pinch growing tips to keep the plant bushy.
  • Take cuttings every spring — Pilea propagates readily and parent plants benefit from the trim.

Common Problems

Wilting is usually thirst — water and the plant perks up within hours. Yellow lower leaves with mushy stems mean overwatering. White cottony spots on stems are mealybugs; dab with rubbing alcohol on a cotton swab.
