What is the common name for Juniperus horizontalis 'Wiltonii'?

Juniperus horizontalis 'Wiltonii' is commonly known as Blue Rug Juniper. This ground-covering juniper is appreciated for its low-growing habit and extensive spreading, making it an ideal choice for erosion control and landscape applications. The foliage typically has a blue-green color that provides visual interest throughout the year, particularly in cooler months when it can exhibit a more pronounced blue tint.

The name "Blue Rug Juniper" specifically reflects its dense, mat-like growth pattern, resembling a rug that can effectively cover ground while also serving functional and aesthetic purposes in various landscape designs. The other options do not accurately describe this specific cultivar and may refer to other types of junipers with different characteristics or growth habits. For example, the name "Blue Pacific Shore Juniper" usually refers to a different species or variety, and "Compact Andorra Creeping Juniper" denotes a distinct cultivar with its own unique traits. Similarly, "Dwarf Japanese Garden Juniper" refers to yet another variety, not related to Juniperus horizontalis 'Wiltonii'. Therefore, recognizing the correct common name helps in identifying the plant accurately for horticultural practices.
