Cordyline, also known as the ti plant and Hawaiian good-luck plant, are among the most colorful foliage plants. Cordylines add a touch of the tropics to any garden and take up very little room. They are perfect for adding the layers of foliage in a tropical garden. They look good from the moment they are planted and give an instant look to the garden and add year round color. They are easy to grow and need little maintenance. The majority of cordylines prefer bright light or minimal shade.
