Cordyline indivisa is a monocot tree endemic to New Zealand, where it is called mountain cabbage tree or bush flax. It is also known as the Broad-leaved cabbage tree, or Tōī.
Dracaena spikes are actually not dracaenas at all, but are members of the cabbage palm genus (Cordyline spp.); C. australis and C. indivisa are among the species that are commonly sold as dracaena spikes. Small dracaena spikes are staples in container gardens, but they can quickly outgrow the growing space and should be transplanted to a larger container. Although the average height for dracaena spike houseplants is only about 2 feet, they can eventually grow to full tree size. A dracaena spike plant is well suited for beginner gardeners because they are relatively easy to care for and take a long time to outgrow their containers.
