Tropical Landscape Bed - This lush bed contains only 4 plants. The contrast in heights & color give it a well-balanced look. All of the plants will work for zone 9 (except palm-see below for alternatives), but a very cold night or frost may cause some to have foliage damage or die back to the ground-returning in Spring. Christmas Palm Tree [Queen, Foxtail, and King best suited for zone 9]. Elephant Ear (Colocasia). Hawaiian Ti Plants (Cordyline Terminalis). Philodendron (Xanadu).
We were influenced by the many lush tropical gardens in our coastal neighbourhood and overseas, too, she says. Tropical plants are also amazingly hardy. It also helps that Bilgola is full of red volcanic soil so everything grows really well! - Jolene's Gardening
