Gardenia
Gardenias are one of the more commonly spotted types of exotic flowers in home gardens, though they are native to tropical and subtropical regions of Africa and Asia. Interestingly, the gardenia actually belongs to the coffee family, Rubiaceae. It forms in evergreen shrubs and small trees, which can grow to a whopping 49 feet tall.
The leaves are broad and shaded in glossy dark green. The flowers can either be solitary or clustered, in either white or a pale yellow. Each flower is tubular with 5-12 petals that spread to nearly 5 inches. Gardenias blossom in mid-spring to mid-summer, and are often heavily and delightfully scented.
