Tropical flowers need habitats that are warm and moist year-round, such as Southeast Asia, Florida, Hawaii and parts of South America. Although you can grow tropical plants in cooler areas, they must be transported indoors when low temperatures hit. When identifying tropical flowers, some factors will vary. But all tropical flowers have a couple things in common, such as large size and colorful flowers.
Observe a plant's foliage color. Tropical flowers' foliage usually are greener than other plants, ranging from a bright to deep emerald hue. Also, tropical flowers usually bloom on thick and lush leaves.
Take into consideration the size of the tropical flower and foliage. This variety of plants can grow quite large and usually does in the wild. For example, the macaranga grandifolia has leaves that grow up to 2 feet wide, while the bird of paradise plant's flowers can grow up to 1 foot by 1 foot.
Examine the flower's color. Tropical flowers are known for their bright or rich coloration in a wide varieties of hues, from deep purple orchids to the hot pink lokelani. Colors may range from cream or pink to bright orange and bright red.
Observe the flower petals, because tropical petals are more spongy and thicker than others. An example is the ginger petal.
Take a picture of the tropical flower if you cannot identify it. Bring it to a tropical nursery or use a website to research and identify it.
