Beautiful mele, delicate crown flowers and other fragrant blossoms — favorites of Queen Lili'uokalani — will be in abundance Sunday, at 'Onipa'a: A Birthday Celebration for Queen Lili'u-okalani.

The free event will feature exhibits on Hawaiian history and culture, Hawaiian music and free tours of 'Iolani Palace. It's organized by the Hawai'i Pono'i Coalition, an organization committed to educating people about Hawai'i's history, culture and Native Hawaiian people.
