Tropical and exotic flowers are distinguished by their unusual foliage and colorful, flashy blooms that light up the garden to create a focal point to the space. Oftentimes, exotic flowers are multicolored and fragrant with large foliage that is just as dramatic as the blooms. Grown in a wide range of shapes, sizes and colors, tropical plants are ideal planted alone in containers or grown among other tropical flowers to accent the garden with vibrant colors.
Canna (Canna 'Pretoria') is a tropical perennial flower with a vigorous growth rate and clumping habit.

The deep tangerine blooms on canna 'pretoria' are speckled and edged with bright yellow to create a showy garden display. The variegated foliage on canna is bright green and yellow. Versatile and hardy, canna 'pretoria' is tolerant to heat and humidity and thrives along pond edges or in shallow water.

Ginger lily (Alpinia japonica) is a tropical, evergreen perennial flower that grows in upright clumps. It grows up to 2 ½ feet tall and wide and is known for its flowers that droop from the ends of each leafy stem, rather than rising out from the plant itself. The white, summer-blooming, tubular-shaped flowers on ginger lilies are striped with white and appear on the spiking inflorescence. The green, lance-shaped, 1 ½ inch-long and 3-inch-wide leaves on ginger lilies grow at the base of the plant and help to create the clumping habit. Ginger lilies grow best in part shade and well-drained, nutrient-rich soil that is medium to wet in moisture. They are suitable to grow in USDA zones 8 to 11.
