Many shrubs have beautiful blooms and evergreens are common landscape plants, but shrubs with year round greenery and showy blooms are not as easy to find in plant hardiness zone 6. There are a few plants that meet your needs, but your choices are limited. A little extra preparation and planning can make your landscaping more successful.

Test the soil for nutrients and pH so that the soil chemistry is correct for the plants you choose.

Note the requirements for sun and water your selected plants need.

Proper soil structure and drainage are necessary for a thriving landscape.

The following plant varieties have zone 6 cultivars available, so when choosing your plant material check the tag to be sure the cultivar is recommended for zone 6. Also make sure the mature height and width will fit into your landscape bed.

Some years these plants may be semi-evergreen depending on how harsh our winter may be or how protected the plant is in the landscape.
