Cordyline Red Heart A dwarf cabbage palm, Cordyline australis Red Heart is a small, palm-like, evergreen tree forming an upright trunk eventually. The long, strap-like, leathery, arching leaves are olive-green, with red bases, which form the ‘red heart’. Trusses of white flowers are produced in summer when the plant is mature, but this is a plant grown more for its foliage. Cordyline Red Heart ​​needs minimal pruning, but dead or damaged leaves can be removed in spring. Give a thick, dry mulch over winter in colder areas, or plant in a container (which will keep it small) and bring it in over winter. Makes a good house-plant.
