Storing Rose of Sharon, Wisteria, and Hibiscus Seeds Over Winter

To maximize germination, store seeds dry and cold over winter rather than sowing in fall where cultivation may disturb them.

Storage Protocol

1. Dry pods on paper towel/bag for 3 days.
2. Extract seeds; dry 3 more days.
3. Place in zip-top bag inside a sealed container in the refrigerator.
4. Sow outdoors after last frost, or start indoors 6–8 weeks earlier.

Cold, dry storage mimics natural dormancy and improves spring germination rates.
