Dusk rose

"Dusk Rose tea eases fever, everyone in Meereen knows that. Especially the slaves who have to make the tea."

- Daario Naharis

The Dusk Rose is a type of vegetation that exists in the region of Slaver's Bay on the continent of Essos.

Dusk Rose tea eases fever, and is a commonly known local remedy around Meereen - particularly for the slaves who have to make the tea.

Season 4
Daario Naharis gives Daenerys Targaryen a Dusk rose in a handful of flowers he has picked for her, ostensibly to show her the lay of the land around Meereen, but truly a thinly veiled attempt to woo her.
