Oriental lilies have interestingly been cultivated for a longer period of time than most plants from around the world and are native to the lily species of Korea and Japan. They have been found in gardens for more than 3,000 years, growing up to 6 feet tall. Although horticulturalists have been breeding various hybrids of this flower, its original physical form consists of three blooms on each stem with an average flower length of about 20 inches. Due to their relatively large size, rich color and pleasing smell, Oriental lilies have been a long-time favorite of many plant and flower enthusiasts.
