Top Shrubs for Fall Performance

Shrubs have always been the backbone of good garden design, but with recent improvements to flowering, foliage color and plant form they are becoming popular for more than their structural assets.   

The merits of this new generation of shrubs transform their purpose from hedges and backdrops to something more like a perennial; a low maintenance perennial with interesting attributes in each season.  Many of the shrubs are especially dramatic when the garden is clothed in the brilliant hues of autumn. 

Here is a list of a few exceptional shrubs for the fall garden.

Proven Winners Caryopteris Sunshine BlueCaryopteris SUNSHINE BLUE®
