Plant Needs
Sunlight
Full sun to partial shade; full sun promotes abundant catkin production, while partial shade is tolerated in warmer climates
Watering
Water deeply when the top 5 cm of soil dries out; established plants tolerate short drought periods but prefer consistent moisture
Temperature
Extremely cold-hardy to -20°C; withstands harsh winters and avoids prolonged temperatures above 30°C to prevent leaf scorch
Characteristics
- Leaf: Oval to rounded leaves with soft grayish down on undersides and serrated margins
- Flower: Silvery fuzzy catkins (male catkins turn yellow with pollen); no true petals
- Stem/Bark: Slender gray-brown stems with smooth young bark, becoming fissured with age
Care Guide
Watering
Keep soil consistently moist during active growth; increase frequency during dry spells
Fertilization
Apply a balanced slow-release fertilizer once in early spring. Over-fertilizing may reduce catkin production by promoting excessive leaf growth
Eggshell powder top-dress：Crush dried eggshells into fine powder, sprinkle a 1 cm layer on soil surface, and water lightly to release calcium gradually; avoid raw eggshells to prevent odorPruning
- Prune dead, damaged, or crossing branches in late winter before new growth begins
- Thin overcrowded stems to improve airflow and encourage robust catkin development
- Trim to maintain desired shape; avoid heavy pruning as it may reduce next year's catkin yield
Toxicity
Warning: this plant may be toxic.
Pets & Humans

Humans: Contains salicin; large ingestion of bark or leaves may cause stomach pain, nausea, or diarrhea
Garden Uses & Culture
