Be fortunate enough to enjoy a garden in a frost-free tropical region and you’ll add many bromeliads to the planting beds and branches of trees or palm trunks. These home garden plants come in all sizes, shapes and colors. The most common type of bromeliad commercially available has overlapping, droopy leaves arranged around a deep cup in the center. The leaves may be gray, maroon, dark or light green, solid, striped or spotted. In all species, bromeliad leaves have permeable scales that collect water and nutrients when there is moisture in the air and seal to prevent moisture loss when the air is dry. When in bloom, a flower spike juts from the center. The bracts of the flowers often contrast with the bright color of the fruit for a fanciful display. Most species produce inedible fruit. One notable exception is pineapple, possibly the most familiar, and certainly the most delicious, of all bromeliads. Gardeners relish using bromeliad home garden plants since they provide either ornate foliage or produce colorful flower stalks called inflorescences that last for weeks or months.
