Shrubs and vines provide the vertical accents for most gardens. By judicious selection, it is possible to enjoy colorful, carefree bloom from early spring into fall. Many species offer glorious fragrance and handsome foliage to complement their flowers, and they make ideal companions for bulbs and ground covers that prosper in the shade they produce around their feet. Occasional pruning is advised to create the best shape and the most bloom, a process both easy and pleasant.
