Cultivated plants are those planted and grown by humans, but some of these plants can also be found growing in a wild-appearing state, such as in abandoned fields or gardens, overgrown former homesites, garden waste dumping areas, or in other semi-wild places. Here in Hawaii, it can be surprisingly difficult to determine if a plant is truly wild-growing or not. Although these cultivated plants are not officially recorded as growing wild here, some of them may be in the future.

Listed below are some Hawaiian cultivated flowers and plants, some of which can appear to be growing wild here.
