Which species is known as the Blue Star Juniper?

The species known as the Blue Star Juniper is Juniperus squamata. This plant is recognized for its striking blue foliage and compact, mounding growth habit, making it a popular choice for ornamental landscaping. The leaves of Juniperus squamata are needle-like and have a distinctive silvery-blue color, which gives it its common name, Blue Star Juniper. Its growth pattern and color make it particularly appealing for use in rock gardens or as a low hedge.

The other species listed do not share the same characteristics or common name. For instance, Juniperus sabina, commonly known as savin juniper, typically has a more spreading growth habit and darker green foliage. Juniperus procumbens, or Japanese garden juniper, is known for its prostrate form and green to gold coloring. Picea glauca, on the other hand, is a species of spruce, not a juniper, and is recognized for its conical shape and light green to bluish foliage.

Thus, distinguishing the unique attributes of Juniperus squamata in terms of both appearance and nomenclature solidifies its identification as the Blue Star Juniper.
