For many of us, it's not too soon to be thinking about planting shrubs when the ground warms up. For the homeowner with a small piece of land or condo plot, or the gardener who wishes to spend more time enjoying the landscape than pruning it, dwarf shrubs are perfect choices.

If you’ve never heard the term “bones of the garden,” it’s not as peculiar as it seems. Landscape designers use the term to describe the structure or “skeleton” of the garden--the plantings which draw the eye to lines and structures, allowing other elements to flow from those main elements. Large shrubs have specific functions, as do trees. But the smaller shrubs are the workhorses of the garden, tying together or dividing different planting areas to present a pleasing picture.
Small shrubs are defined as those reaching 5 feet or less at maturity. The true dwarf varieties seldom grow to more than 3 feet. These charming woody ornamentals can grace even the smallest yard or garden plot, as long as you take the time to choose the right plant for the right place.
Hardiness is very important; this includes not only the winter hardiness, but other seasonal factors such as drought, extreme heat, rainfall, and drying winds. Soil conditions, level of moisture, light requirements, and exposure also play an important part in how well a shrub will perform.
Another thing to consider is growth rate. Slow-growing specimens require less maintenance, so are better suited to areas where other plants with similar needs are located. This form of planning is called zones of maintenance.
When should you plant new shrubs?
Specimens that are known to be difficult to transplant or slow to become established should be planted in spring; this allows them a longer period of time to settle in. The majority of woody ornamentals and trees can be planted in the early fall as they enter a phase of growth slow-down in preparation for dormancy.
If you’re planning to re-landscape your yard, or are just looking for some new and interesting elements in the garden, take a good look at dwarf shrubs. They’re little, but they are mighty!
