This rare flower is native to the Feywild. It has a large ember-colored bushy corolla, being very similar to a Peony (Paeonia spp.) shape. Crushing the flower head emits a special fragrance, that if crushes right beside a sleeping creature's nostrils is strong enough to awaken it. This effect is strong enough to awakened even creatures put asleep by magic, though is not strong enough to dispel higher-level magic in an unrefined state
(Game terms: Sleeping spells up to and including 4th level may be dispelled by crushing a flower head next to a person's nostrils. Dispelling magical sleep above 4th level requires an extract to be effective. Both versions are consumed upon use as the fragrance evaporates into the air.)
