Geraniums offer the gardener the option of a second season of bloom. Unlike many other annuals, geraniums tolerate the increased dryness of the home environment. Bring these annuals inside for the winter, treat it as a houseplant, and you'll have abundant blooms the following season. Geranium blooms add color and pizazz to the garden with clusters of blooms in pink, red and white. This beautiful plant is a must for the annual garden, container and hanging baskets.
