"I'm a big fan of sangrias and was experimenting with edible flowers. The tangy flavor of hibiscus blends very well with the sweet wine and fruit flavors in this drink! I love to eat the fruit in sangria, so the fruit to liquid ratio in this recipe is high. Feel free to reduce the fruit if you'd prefer!"
Bring water, hibiscus petals, honey, cinnamon sticks, and cardamom to a boil in a large pot. Remove from heat and allow to steep for 1 hour; strain. Stir wine, brandy, brown sugar, elderflower syrup, and triple sec into strained hibiscus water until sugar is dissolved. Add pineapple, apples, strawberries, oranges, and lemon. Refrigerate 8 hours or overnight.
