Red Hibiscus, the Hawaii State Flower.
Sent by Becky from Hawaii, USA.
The hibiscus, all colors and varieties, was the official Territorial Flower, 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 yellow hibiscus which is native to the islands was selected to represent Hawaii. For this reason, you will see many older photos and postcards with the red hibiscus, or any other color for that matter, as the state flower. These weren't incorrect at the time. (Source)
