Juniperus Blue Arrow, also known as ‘Rocky Mountain Juniper’ and holder of the prestigious RHS Award of Garden Merit,  is an evergreen conifer that is prized for its unique shape and beautiful blue-grey foliage. Native to the mountains of central and southwestern China, this species has been grown in cultivation for centuries.

The Blue Arrow has a narrow, upright growth habit that makes it an excellent choice for use as a accent or specimen plant in the garden. It can reach up to 2.5 metres in height with a spread of only 1/2 metre, making it an ideal option for small spaces or narrow garden beds.

The needles of the Blue Arrow are arranged in a spiral pattern along its slender branches, adding both texture and colour to the garden. In the Winter months, the foliage of this plant takes on a purplish-blue hue, adding even more interest to the landscape.

While it is not a commonly known species, the Juniperus Blue Arrow has been growing in popularity in recent years due to its unique appearance and versatility. If you are looking for an eye-catching conifer that is both low maintenance and easy to grow, the Blue Arrow is a perfect choice.

How to care for your Juniperus Blue Arrow

  • Light: Prefers full sun to partial shade, but can also tolerate some light shade.
  • Soil: This plant is adaptable to a wide range of soil types, but prefers well-draining soil. If your soil is heavy or poorly drained, amend it with compost or sand to improve its structure.
  • Watering: It is drought-tolerant and does not require frequent watering. Water it deeply and infrequently, and avoid overwatering which can lead to root rot.
  • Fertilisation: This plant is not heavy feeder and does not need to be fertilised regularly. If you wish to fertilise, you can use a slow-release fertiliser once a year in early Spring.
  • Pruning: It is a slow-growing plant and does not require frequent pruning. If you need to shape or control its size, you can prune it after it finishes blooming, in late Spring or early Summer.
  • Winter Protection: The Blue Arrow is hardy down to a temperature of -20˚C. However, in very harsh winters, it may be beneficial to protect it with a layer of mulch or a Winter-proof covering.

By following these simple care tips, your Juniperus Blue Arrow will thrive and provide you with years of enjoyment in your garden.
