Hedge Selection Tips

Hedges are grown primarily for privacy and beauty and there are too many good choices to list. When considering which plant to use for a hedge, narrow your selections down by trying to define what characteristics you desire.

Are you interested in a formal clipped hedge which requires pruning regularly or are you interested in a more "natural" hedge as a screen which could be a loose grouping of shrubs, perhaps offset from each other.

Think about the other features of the plant you may want. Are you set on having an evergreen or a deciduous hedge?  Are you interested mainly in foliage or blossoms? Some hedge plants are people friendly and others have stickers and are not.  Stickers could be good or bad, depending on your objective.

Importantly, the selection process should choose plants shown to grow well in our cold hardiness area--Tulsa is mostly zone 7. Also think about what type of soil you may have and the amount of sunlight in your planting space. Some of these hedge plants need shade while others have to be in the sun for best performance.

Keeping the above criteria in mind, there are several groupings from which to select. Most of these groups, or genera, will have many unique species and cultivars. This list is of the most commonly used hedge plants and is just a fraction of possibilities.  For more information OSU has an excellent fact sheet, "Selecting Shrubs for the Landscape", online or at the OSU Master Gardener office. Other good references are Carl Whitcombs "Know it and Grow it" and Michael Dirr's "Manual of Woody Landscape Plants".

The following tables are suggestions for hedge plants--divided into needled evergreens, broadleaf evergreen and deciduous.
