Plant Taxonomy of Blue Rug Juniper Plants:
These plants are low-growing evergreen shrubs. Plants in the Juniperus genus are considered to be conifers, although, granted, most people would mistake the cones for berries. This mis-identification is perpetuated by the fact that you will often hear talk of these so-called "berries," which are used to flavor both cuisine and gin.

More on Blue Rug Juniper Plants and Similar Groundcovers:
There are numerous types of junipers, and they come in a variety of heights, forms, colors (golds, blues and greens) and textures. But note that not all junipers are suitable for groundcovers. Some junipers are trees, while others fit the more usual image of "shrubs," i.e., plants that stand anywhere from knee-high to chest-high. Such plants are suitable for privacy screens and hedges.
But the focus of this article is the vine-like, low-growing junipers. Where and why would you grow such plants? Although they can be grown on flat land, juniper groundcovers are most prized as plants that can cover a sunny slope, where they serve 3 purposes simultaneously: erosion control, weed control and eliminating the need to mow where footing is treacherous. In addition, many other plants find it difficult to thrive on sunny slopes, where water runs off so quickly that the vegetation is apt to go thirsty. But juniper, on the contrary, tends to be relatively drought-tolerant ground cover and craves excellent drainage.
Many varieties besides Blue Rug juniper plants are suitable for groundcovers. A green cultivar of Juniperus horizontalis, namely, 'Prince of Wales,' purportedly grows even more quickly, while another cultivar, 'Mother Lode,' bears greenish-gold foliage. Meanwhile, the 'Pancake' cultivar stays smaller than these, both in terms of height (an amazing 2"-3") and spread (2').
Other species of juniper groundcover are Juniperus procumbens and Juniperus squamata. The 'Blue Star' cultivar of the latter provides another option for those who seek that cool blue foliage. But Blue Star juniper will get taller over time (up to 3') than Blue Rug and doesn't spread as much, proportionately (4').
