Blue star juniper is a small, mounding dwarf juniper grown for its blue color and interesting scales (leaves). Rather than having long, feathery branches like other short junipers, it has short branches that form a small, irregular mound shape. It is often used as a dwarf conifer to provide year-round beauty in the landscape. It is less expensive than specialty dwarf spruces and pines.
Its light and medium blue color is quite beautiful. Blue star juniper grows best with some protection and regular watering.
There are several blue star junipers growing at the Xeriscape Garden. They are attractive shrubs, but their shape gets more irregular as they age. Some homeowners prefer to replace them every 5 years or so when they lose their attractiveness.
Blue star juniper is a good option where a blue-colored, small evergreen shrub is desired, but grows best with some protection.
Junipers require little maintenance after establishment. Watering once per month during the winter will help prevent dehydration.
