Harvesting and Storing Althea (Rose of Sharon) Seeds

Althea (Hibiscus syriacus), also called Rose of Sharon, produces seed pods that turn brown when ripe. Collect just before they split.

Seed Processing

1. Harvest brown, unopened pods.
2. Dry indoors a few days.
3. Store in a sealed jar in a cool, dark, dry place.
4. Sow in spring; no stratification needed.

Seedlings may vary from parent if it’s a hybrid. For exact clones, use softwood cuttings in early summer.
