Storing Dried Hibiscus Flowers for Longevity

To maintain the vibrant color and tart aroma of your dried hibiscus:

Cool, Dark Place: Protect the calyces from direct sunlight, heat, and moisture, which will cause the color and flavor to fade.
Shelf Life: Properly stored, dried hibiscus can remain potent for up to 1 year. Indicators of staleness include a faded color and a noticeably less tart aroma.
