The foliage on the Kleim’s Hardy Gardenia are a glossy, dark green and provide year-round color. They are an attractive backdrop for the flowers. From late spring through summer, it produces fragrant, single, pinwheel-shaped flowers. These are different from the common double-petaled gardenias, giving the plant a unique, star-like look. They are creamy white and have the classic, sweet, jasmine-like scent.
