Many of the plants that project the tropical look aren't winter hardy below 15 to 20 degrees (USDA Zone 8). But many of these plants make excellent houseplants and can be overwintered in the home, spending summers in your garden.

The handsome gray-green foliage of the hardy sugar cane provides a wonderful tropical feel and vertical accent to the garden. The effect is heightened in fall when flower panicles are produced in large numbers and tower to as much as 15 feet. The plumes begin as soft pink, open to silver and look great through the winter. Hardy sugar cane performs well down to USDA Zone 6.
