Exotic flowers are grown to add color and excitement to what may otherwise be a boring landscape. Also known as tropical flowers, exotics are generally unusual or rare flowers. Just the term "exotic" may frighten some people who are clueless as to how to select or care for them, but they can be successfully grown. These striking flowers are also used as cut flowers in bouquets, notes the Oh My Apartment website.
Exotic flowers usually originate from foreign countries. Because they typically come from warm, tropical regions they can't survive in cold areas. According to Michigan State University, temperatures lower than 45 to 50 F can damage these plants.
Lilies come from the Lilium genus and have underground bulbs composed of overlapping scales containing stored food. Most lily flowers have three petals and three sepals. These exotic flowers come in various shapes and colors.
Irises are exotic flowers that are often confused with lilies. They come from the same family as crocus, gladiolus and freesia, notes Flowers-cs.com. They generally have erect, flat leaves and flowers containing bright sepals, which can either droop or spread.
The exotic flowering plant known as ginger, which comes from tropical Asia, produces purple and green blooms in cone-like, thick clusters.
Many exotic flowers can be used in indoor gardening and make interesting house plants. According to the Oh My Apartment Ratings website, exotic flowers such as begonias, hoyas, sarsprites and sarracenias are ideal plants for indoors.
Begonias come in many varieties, such as miniatures, which are especially suited for indoor garden. Hoyas, which are tropical and subtropical plants, produce exotic flowers that can be excellent for window displays. Sarsprites produce white flowers and can be grown in small pots on window sills. Sarracenias are exotic tropical flowers with red veins and white markings.
Many exotic plants can become invasive, such as those exotic species that were introduced into the South's natural regions as landscape plants decades ago, says North Carolina State University. Continually moving exotic plants into suburban environments can cause many invasive plants to become problematic years later.
The exotic flower known as the Bird of Paradise (Caesalpinia gilliesii) is considered to have poisonous seed pods, according to Colorado State University. This native flowering plant of Uruguay and Argentina grows erect and produces showy yellow flowers with long hot-pink or red stamens, roughly 4 to 5 inches long. Its poisonous seed pots are curled and are tan or brown. If consumed, the seed pots can cause nausea, diarrhea and vomiting, according to North Carolina State University.
