Shrubs, to me, are like See's candy boxes to a chocaholic.
The reason, in three words: Lushness, variation, dependability.
Using shrubs with varied colors and shapes of foliage, and with different flowering seasons, gives a mature, full garden border all year long. Leaving one foot gaps between the shrubs lets you add seasonal annuals, garden ornaments, or even decorative stones or gourds, to change the look around without a lot of cost or work.
