Adding structure and an aspect of year-round permanence to any yard, small shrubs are excellent for enhancing the perennial border. Thought of as the spine and bones of good landscaping, small shrubs hold the soft body of flowers together and add consistency between areas. Well-chosen selections integrate with perennials to add interest for more than just one season. Not only do they add support for perennials in late summer but also they provide definition to the bed throughout the year. Though shrubs take longer to reach maturity, their outstanding foliage, lovely flowers and attractive shapes and forms add to the beauty of the garden.

Choose Shrubs That Promise Year-Long Interest

The ideal shrub for the mixed border has outstanding foliage – deep green, purple, gold, silver, or even variegated. Its leaves may be glossy, soft or even fuzzy to touch. Colorful veins or other variations may mark its foliage to seize your interest throughout the seasons. And, certainly, the ideal shrub has flowers. Late-blooming flowers liven up the border during the tired end-of-summer days, while early-blooming varieties add excitement to a garden just bursting into spring. You’ll also want to take into account flower color when working shrubs into a planting scheme. White is a delightful and safe choice because it harmonizes with all other colors. Consider also mellow blues, pinks and other pastel shades to add a peaceful mood to the garden. Bold colors of yellow, orange or red will add a warm, daring feeling and dramatic interest. In fall, colorful leaves cover the ideal shrub before falling to the ground. And in winter, twisted, colorful branches and bright berries provide visual interest even under a layer of frost or snow.
