The pua aloalo, or hibiscus is the
official Territorial Flower of Hawaii, adopted in the early 1920s. At
statehood in 1959, the first state legislature adopted many of
Hawaii's symbols as part of the Hawaii Revised Statutes (HRS, state
laws). It wasn't until 1988, however, that the Hawaii legislature
adopted the yellow hibiscus, which is native to Hawaii, to represent
Hawaii as the official flower of Hawaii.
