Wasabi flowers are slightly sweet with a mildly sharp aftertaste. In Japan, almost every part of the wasabi plant is eaten, including the wasabi flowers. Wasabi flowers are small, cross-shaped white flowers that bloom from autumn to early summer. They are decorative and very tasty. Both the stem and the flowers have the unique wasabi flavor; slightly sweet with a mildly sharp aftertaste. Serve them, for example, on sushi or as a spicy accent on desserts.
