Juniperus scopulorum 'Skyrocket'
This plant has a tall and extremely narrow, columnar growth habit. Its short, compact, silvery blue foliage is evergreen with virtually no change from season to season. It's a very striking, dramatic plant when used as a cluster planting against a large fence or building or in formal plantings. The tallest, narrowest juniper out there. Beautifully elegant for use around large entryways, gates, or even just to hide that old gutter downspout. FAST GROWING!!!!
There is much confusion out there in regards to the Skyrocket juniper variety versus another variety called Blue Arrow Juniper. There are several opinions as to whether there is any difference between the two varieties, or whether they are even two separate varieties at all. Our opinion / stance on this subject is that the two names are synonymous, and both pertain to the same plant variety. We have grown specimens that were labeled as both Skyrocket, as well as Blue Arrow - multiple specimens of each, and all were grown within close proximity to one another. We noticed absolutely NO distinctions between the two, no differences to speak of whatsoever.
We choose to grow Skyrocket, and market them as such, due to the fact that Skyrocket was the first of the two varieties ( Skyrocket & Blue Arrow ) to be introduced & developed. Skyrocket has been around for years...whereas Blue Arrow is a fairly recent market introduction. There are also several sources within the landscape / horticultural industries that still list Skyrocket Juniper as a member of the Juniperus virginiana family - but proper classification of this variety would put them in the J. scopulorum family.
Plant Facts & Specifications
15 - 20 ft
2 - 3 ft
Moderate to fast ( 10" - 18" avg per yr )
3 - 8 ( if unsure of your zone, please use zone finder below - or check out our Hardiness Zone Map & Information Page )
Full sun preferred, but will tolerate some partial shade as well. Growth rate, and foliage density will both suffer slightly when planted in shady locations. Sometimes has trouble dealing with high heat & humidity, as well as high night time temperatures.
Average to slightly acidic & sandy - well drained. Regular mulchings are very beneficial.
--Foliage Color & Texture:
Evergreen - very light green to yellow base, with nice bright yellow outer foliage. Minor bronzing in winter months in colder climates. Medium - fine texture.
--Flower, Cone, Or Berry Facts:
None to mention
--Diseases / Insects:
Phomopsis blight, canker, and Cedar Apple Rust have all been spotted on this variety....as is the case with most any J. scopulorum varieties. Regular yearly inspections are recommended to monitor any possible problems. The occurrence of both Phomopsis, and canker can be more prevalent if conditions are overly moist / wet.
Spacing of approx 2 1/2 feet apart is recommended for most privacy screen or border plantings.
--Deer Resistance Rating: Lowest Resistance [ 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance
--Fertilization / Feeding:
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
