Taro is in line to become Hawai'i's official state plant this summer.

Acting Gov. James "Duke" Aiona signed the bill into law Wednesday.

Taro was to have become the state plant last year. But lawmakers made a mistake when they initially passed the measure. It wouldn't go into effect until the year 2025.

This year, they amended the legislation to make taro the state plant as of July 1.

Aiona also signed a bill designating the Hawaiian monk seal the state's official mammal.

Aiona is acting governor while Gov. Linda Lingle is out of the state to attend Israel's 60th anniversary celebrations.
