Whether you are selecting shrubs for the foundation plantings around the
house or for a shrub border in your yard, choose shrubs that will bloom
at different seasons. Most of the flowering shrubs that are available
bloom during the spring. Once some shrubs have finished blooming, they
have no other ornamental features. The interest in your landscape will
be lost, unless you have selected some summer-blooming shrubs. Attempt
to design your landscape so you can have continuous shrub bloom from
early spring through late summer.
