Juniperus horizontalis is commonly called creeping juniper. It is found over a wide range from Alaska down to the Great Lakes. With such a wide range many different forms are available. Height, foliage colour and growth habit differ.
One of the most useful ground cover conifer varieties, it grows well in colder climates, however it is versatile and is regarded as hardy in USDA Zones 3 to 9
Where to Plant Juniperus horizontalis
An excellent choice for any well drained soil, and especially useful as a low maintenance ground cover in difficult situations.
Plant the creeping Juniper in early spring and make sure you provide some moisture through the first summer. A good layer of mulch can be helpful. This early planting gives the plant a chance to establish a strong root system before the heat of summer and then the first cold winter.
Not suited to areas subject to foot traffic, and Junipers do not like hard pruning so choose your planting position with this in mind.
And yes, you can plant some of the smaller and slower growing types in containers.
