Juniperus scopulorum 'Blue Arrow' / Blue Arrow Rocky Mountain juniper

Juniperus scopulorum 'Blue Arrow' is a fairly fast growing, narrow, upright selection of Rocky Mountain juniper with dense branching holding bright, blue-green foliage and silvery berries in winter. After 10 years of growth, a mature specimen will measure 12 to 15 feet (4 - 5 m) tall and only 2 feet (60 cm) wide, an annual growth rate of 15 to 18 inches (37 - 45 cm).

'Blue Arrow' is a good choice for those wanting a formal, Mediterranean-style garden, but live in a climate that is too cold for Cupressus sempervirens to survive.

This cultivar originated as a seedling selected in 1949 at Pine Grove Nurseries, Clearfield, Pennsylvania, USA. Many growers consider it to be an vast improvement over the older, ubiquitous, Juniperus scopulorum 'Skyrocket.'

Could these be trimmed at the top to maintain a desired height?

David Olszyk



Hi David. Do you (or anyone else) know when I can trim my Blue Arrow? Some websites mention September. Also a website mentioned it's best to trim in late winter (when the heavy frost is passed). Can you advise? I live in the Netherlands. September is autumn and +/- 15 degrees C. Late winter +/- 5 degrees C (and the spring sets in around march/april.


Do you need to shape it. Mine is getting 'floppy' as it grows. The branches are starting to act as if they are too heavy to stay upright.


Can you tell me about the root system? Can these be planted up next to a foundation?

David Olszyk

root system can be described as fibrous, spreading and adventitious. Feeder roots will spread out several feet from the crown in search of water and nutrients.

I am considering a 'Blue Arrow', I understand it stays about 2 feet wide. I have a small yard. I live in Colorado and concerned about how it does with snow weight. How does it hold up?I find nothing on this subject on the garden websites. I heard the Woodward (Plant select) does well with snow weight but I don't like the looks of it as well. Any help would be appreciated.

David Olszyk

Hi Barbara ... snow and ice will definitely splay those fine fastigiate branches. If you don't want that that to happen, try doing what I do: before expected snow or ice, get a bunch of old bicycle tubes and and wrap that plant. As the snow event is taking place. Give the plant a few whaps with a broom before it builds up too much.

Does anyone know where these can be purchased online? Monrovia ships them, but not to Lafayette, Indiana, where I live (not sure why since it should do OK here). The local garden centers do not carry them either.

How far apart should these be planted from one another, and how deep? Thank you.

David Olszyk

if you're trying to create a mass planting, you can plant these as far apart as you please. As for depth, always plant to a depth that the root flare is visible. Planting too deep will virtually guarantee to suffocate the root system within 15 years of planting.

Do deer like to eat these trees?

David Olszyk

deer are extremely local problems. If they're starving in your neighborhood, any non-toxic plant is fair game. Junipers are non-toxic.

I want these for the front entrance which is fairly well shaded . I’m ok if they don’t reach mature height - but will they still work in the space ?

David Olszyk

the more shade, the less dense the foliage and branching. They'll likely "open up" and look sparse.

I’m thinking of planting these on a ledge behind my house where there isn’t depo soil.
They will be I. Full sun and will have wind protection from house on one side and mature large trees below the ledge on the other. I’m in Massachusetts so there is snow. I
At these a poor choice for that location?
