Tropical flowering plants are usually grown indoors, unless you live in a tropical climate. Some are quite carefree and easy to grow while others have requirements that are almost impossible to recreate in the home environment. The tropics are warm, moist regions where flowering plants generally grow under the canopy of rain forests. Some can tolerate full sun; others require at least dappled shade. Many colorful tropical plants exist, including those with fiery red tones.
Hibiscus Rosa sinensis
Hibiscus is a genus of flowering plants native to the tropics. Hardy to USDA zones 9a to 10b, the hibiscus requires full sun and mildly acidic to mildly alkaline soil. The 'Red Hot' variety has striking red flowers that bloom from mid-spring to mid-fall. Even the foliage of this cultivar is red. 'Red Hot' requires more water than the average hibiscus, especially in hot weather.
Alpinia purpurata, commonly called red ginger, is native to Malaysia. Red ginger also grows in Hawaii, where it is known as Awapuhi, in Puerto Rico and Samoa, where it is the national flower. Red ginger is a tall, evergreen flowering plant that blooms in bright red bracts, which envelope the small white flower of the plant. It thrives in a humid environment with dappled sunlight and consistently moist soil.
Although several hundred species of Anthurium exist, in different colors, it is the red Anthurium that perhaps most strongly evokes thoughts of the tropics, especially Hawaii. This species of Anthurium, though, is native to the Andes in southern Columbia. It is an epiphyte in nature, meaning that it grows on another plant--in this case, a tree. Anthurium requires daytime temperatures from 78 to 90 degrees F and nighttime temperatures between 70 and 75 degrees F.
