Abutilon menziesii, known as Koʻoloaʻula in Hawaiian, is an endangered species of flowering shrub in the family Malvaceae, that is endemic to Hawaii.

Though charming up close, the flowers can be hidden by the much larger leaves and not often visible at a distance.

Although the Hawaiian name ʻula refers to the more commonly seen red color, koʻoloa ʻula flowers are known in a range of colors: pink, pink and white, pale red, maroon, deep purplish-red (wine), salmon, and blond or butter.

[4] It is classified as critically endangered by the IUCN Red List; only about 450–500 plants remain in fewer than ten naturally occurring populations throughout the islands.

[3] The rarity of this plant can be attributed to the alteration of its habitat for agricultural and urban development, overgrazing by livestock and feral animals, and competition from invasive weeds.
