This is a perennial, commonly known simply as “hibiscus”, or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus.
The hibiscus flower is traditionally worn by Tahitian and Hawaiian girls. If the flower is worn behind the left ear, the woman is married or has a boyfriend. If the flower is worn on the right, she is single or openly available for a relationship.
