The variety available means there is a juniper for almost any garden. Whether you are looking for a steely blue groundcover or a tall tree for a privacy hedge, junipers fill the job. The plant that flavors gin will also add flavor to your garden!
Scales and Needles
Junipers are interesting evergreens for several reasons. The foliage is one source of interest: Some have small, sharp needles; others have scalelike leaves; some have both. Immature plants have the sharp needles; as the plant matures, it grows scale-type leaves, which then bear fruiting cones. Consider the foliage for your planting situation. For instance, if you will be planting it near walkways or other spots that get walking traffic, seek varieties that only have scales (needles can be quite sharp and cause a temporary rash on some individuals).
Juniper Care Must-Knows
Their ability to grow in some pretty tough situations with little care makes junipers prized in garden settings. Although junipers handle drought well, they need well-drained soil. They also need full sun for the best growth. (They even tolerate winter's salt spray so work along roads and sidewalks.) Shady spots tend to result in loose, open growth, which reduces the appeal of the plant. Coloring on many of the blue/silver varieties may also be less vibrant in part shade. It is important to note that some of the gold foliage varieties prefer shelter from hot afternoon sun to prevent burning.
They requite little maintenance, just minor trimming and shaping of the plants. Never cut them back to the bare stems in the center of the plants, because this wood is usually too old and tough to set new growth. If you're training juniper into a formal shape, select a variety amenable to regular pruning. Groundcover types are generally not a good choice for that and should be minimally pruned, if at all.
So Many Choices
Junipers come in a wide range of shapes and sizes. You can roughly group junipers into three main growth types: groundcover, midheight or mounding, and tall upright. Each has their own uses and come in a wide variety of colors, shapes, and sizes. As you venture into the world of juniper, it is best to narrow your search down to one of these types and go from there. Within each group, there are still numerous options to choose from, so you'll still have your work cut out for you!
