Introduced Plants: are plants that are not native to an ecosystem. As humans traveled over the planet, they brought with them a variety of species novel to an environment. They intentionally brought many introduced, or exotic, species, such as wheat, potatoes, cattle, pigs, and horses. Many species, however, came uninvited, traveling in the holds of ships or planes, hitching rides on imported produce, or escaping from captivity. Arriving in an ecosystem that evolved without them, introduced species frequently have no predators. Native species may not have the defenses necessary to ward off a novel predator, and introduced species can out compete native species and drive them to extinction or change an ecosystem by altering relationships within it.

The protea was introduced to Hawai‘i as a commercial cut flower crop. Protea cynaroides occur mainly in the southern hemisphere. In southern Africa there are about 360 species, mainly from the subfamily Proteoideae, of which more than 330 species are confined to the Cape Foral Kingdom, between Nieuwoudtville in the northwest and Grahamstown in the east. Protea cynaroides belongs to the genus Protea, which has more than 92 species, subspecies and varieties. Plants in the subfamily Grevilleoideae occur mainly in Australia.
