Cordyline, or ti, are common decorative plants that thrive outdoors in hardiness zones 9-12 but also make excellent houseplants. The name Cordyline originates from Greek; the word kordyle, meaning “club,” is a reference to the plant’s enlarged underground stems. Cordyline typically has leathery leaves shaped like a spear or lance with a variety of colors, including green, red, yellow, white, purple, and purplish-red. Caring for these plants indoors is simple and straightforward, but they must be kept warm, and they need a lot of light. If you plant them outside, do so in the spring.
Some species in this group have fragrant flowers followed by berries. The moderate-growing plant will produce white, pink, or pale lavender flowers that are cup-shaped and sweet-smelling. They bloom in early summer and then small berries will appear after the flowers. It’s more typical for flowering to occur in outdoor varieties, but flowers can appear on houseplants.
