What is the scientific classification of the Blue Rug Juniper?

The scientific classification of the Blue Rug Juniper refers specifically to its botanical designation. Blue Rug Juniper is a cultivated variety of the species Juniperus horizontalis, which is why the correct classification includes this genus and species name along with the specific cultivar name 'Wiltoni.'

This particular juniper is valued for its low, spreading growth habit and striking blue-green foliage, making it a popular choice in landscaping and ground cover applications. It thrives in well-drained soils and is often used in rock gardens, slopes, or as a border plant due to its ability to withstand drought once established.

The other options are names of different tree species or cultivars. Chamaecyparis pisifera 'Sungold' refers to a type of false cypress, Pseudotsuga menziesii is the scientific name for Douglas fir, and Sequoiadendron giganteum is the giant sequoia. None of these options are related to the Blue Rug Juniper in terms of classification or horticultural traits.
