For spectacular beauty, gloxinias rate highly having huge, velvet, bell-like flowers. Native to Brazil, there is a wide variety of colors from which to choose ranging from brilliant crimson, dark red, deep purple and blues in many shades to white, pink, bicolors and some with spots called tigrinas. Additionally, flower forms vary, coming in upright, nodding, single, double and miniature. Miniatures make excellent terrarium specimens which will not outgrow their homes. Commercially, gloxinias make marketable plants throughout the year, especially for Christmas, Valentine's Day, Mother's Day and summer sales.
