Overview
Pilea libanensis is the correct botanical name for the plants traded as Pilea glauca, Pilea Silver Sparkle, or Red-Stemmed pilea. The silver-blue cast comes from a fine surface coating on the leaves, similar to a bloom on grapes.
Care Priorities
- Bright filtered light keeps the silver finish bright.
- Use small pots and refresh mix every year; this species exhausts soil quickly.
- Trim back regularly — the wiry stems get straggly without pinching.
- Take backup cuttings; older plants often decline after two years.
Common Problems
Brown crisp tips are dry air. Yellowing throughout is overwatering. Long bare stems are old age and a signal to refresh from cuttings.

Frequently asked questions
Pilea glauca or Pilea libanensis?
Botanically Pilea libanensis. Pilea glauca is a long-standing trade name with no formal botanical status.
Best for terrariums?

Why are the stems so red?
Red stems are species-typical and intensify in brighter light. Pale stems usually mean too little light.
