Overview
Pilea spruceana is one of about 700 species in Pilea, the largest genus in the nettle family Urticaceae. Native to the northern Andes, the 'Silver Tree' cultivar has bronze leaves with a striking silver central band running down each leaf, named after the 19th-century botanist Richard Spruce. 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.
