Noni (Morinda citrifolia)

There are a few noni plants that can be spotted on the sidewalks on the streets of Oahu.

This ornamental plant is nowadays seen in yards or along side the street on the sidewalk, but it was commonly used as a medicinal plant for native Hawaiians. Although this plant has a nasty odor, everything but the fruits were used medicinally. It has a wide variety of uses such as for coughs to more severe things like for strokes. This would be a very useful ornamental plant to have around.
