Summarize the following:
There are many varieties of the hibiscus flower, but the hibiscus sabdariffa variety is the one that gives you the best flavor. The calyx is the green, trumpet-shaped part at the base of the flower, which will eventually turn red and brittle.  The hibiscus must be pesticide-free if you are using it for tea. It does not have to be pesticide-free if you are using it for general crafts. You can try using this method for the actual flowers too, but you will need to adjust the drying time. Timing is everything here. Find hibiscus flowers that are in bloom, then wait for them to fall. Locate the red calyx, then pick it after 24 to 48 hours. This will ensure that it is ripe. The calyx should pop off of its stem easily. If you have to pull it off, it is not ripe yet. Try again the next day. Cut the calyx from the stem of the flower first. Next, cut a shallow slit down the length of the calyx. Pry open the calyx with your fingers, then pop the seed pod out. Try to keep the calyx intact. Don't throw the seed pods away! Allow the seed pods to dry for 1 week, then crack them open and plant the seeds. Preheat the dehydrator between 95 to 115 °F (35 to 46 °C). Spread the calyxes on the tray in a single layer. Allow the calyxes to dry completely before taking them out of the dehydrator. This will take about 1 to 4 hours. Each dehydrator is different, so follow the instructions on your model carefully. Pour 2 cups (475 milliliters) of hot water over 1 tablespoon (15 grams) of dried hibiscus calyxes. Allow the tea to steep for 10 minutes before removing the calyxes. Flavor the tea as desired with lemon juice, sugar, or honey. Serve the tea hot or iced. If you want a stronger tea, use more hibiscus calyxes and increase the brewing time. If hibiscus tea isn't for you, you can add the dehydrated calyx to homemade potpourri. You can try using it in homemade candles or soap as well, but it would be a good idea to crumble it up first so that it isn't as bulky. Alternatively, you can string whole calyxes onto thread and make a pretty garland for your room.

Summary:
Look for an organic hibiscus sabdariffa and locate the calyx. Pick the calyxes 24 to 48 hours after the flower has bloomed. Cut the seed pod away from the calyx. Dry the calyx using a dehydrator. Use the calyx to brew hibiscus tea. Use the calyx to make potpourri.
