Skyrocket Juniper Juniperus scopulorum 'Skyrocket'
ABOUT
The 'Skyrocket' Juniper, often known for its remarkably narrow and columnar shape, presents itself as a strikingly vertical accent in the landscape. Its densely packed branches grow upward in a tight fashion, resembling a tall, slender pyramid or rocket, a silhouette that truly sets it apart from other conifers. The foliage maintains a rich, bluish-green hue throughout the year, offering a vibrant splash of color even during the colder months when other plants may lose their luster. The leaves of 'Skyrocket' are small, scale-like, and tightly appressed to the branches, which gives the tree a somewhat textured appearance up close. Although the individual leaves are hardly noticeable on their own, collectively they create a dense and feathery surface that is soft to the touch. When examined, the foliage may release a characteristic resinous scent that is often associated with juniper varieties, adding sensory appeal to its visual characteristics. While it's typical for 'Skyrocket' Junipers to produce small, berry-like cones, these may not always be prominent or noticeable without closer inspection. These cones can start off as a bluish color, blending with the foliage, before eventually maturing to a more brownish hue. The bark on 'Skyrocket' is fibrous and may exhibit a reddish-brown color, offering a textured look and feel to the sturdy trunk and branches that support the dense growth of the striking foliage.

- Water
The Skyrocket Juniper, prefers dry to medium moisture levels and does not require frequent watering once established. In the first growing season, it is essential to water it regularly to help establish a strong root system. Water the plant deeply once a week, providing about 1 to 1.5 gallons each time, depending on soil conditions and climate. After establishment, decrease the frequency, allowing the soil to dry out between waterings. Over-watering can lead to root rot, so it's crucial to ensure good drainage and to adjust the watering schedule during rainy periods to avoid excess moisture.
- Light
The Skyrocket Juniper thrives best in full sun conditions, which means it needs at least 6 hours of direct sunlight daily. Place it in a location where it can receive unfiltered sunlight throughout the day for optimal growth and health. Although it can tolerate some light shade, too little light can lead to sparse foliage and a less robust form.
- Temperature
The Skyrocket Juniper is hardy and can withstand a wide range of temperatures, preferring climates with temperatures that typically range from -30 to 100 degrees Fahrenheit. Though it is resilient, extreme and prolonged temperatures beyond this range can stress the plant. The ideal temperature for this juniper is between 40 to 70 degrees Fahrenheit for vigorous growth.
- Pruning
Prune the Skyrocket Juniper to maintain its narrow, columnar shape or to remove any damaged or diseased branches. Pruning is typically not required frequently, but if necessary, the best time to prune is in late winter or early spring before new growth starts. Avoid heavy pruning as Junipers do not respond well to cutting into old wood.
- Cleaning
Not needed

- Life cycle
The life cycle of 'Skyrocket' Juniper (Juniperus scopulorum 'Skyrocket') begins with seed germination, which is typically slow and can be improved with stratification. Seedlings initially establish a taproot and grow slowly, developing needle-like juvenile leaves. As the plant matures, it transitions to adult foliage with scale-like leaves and begins vertical growth, characteristic of its columnar habit. Sexual maturity is reached within a few years, at which point it may produce cones—female plants produce blue, berry-like cones (juniper 'berries') while males produce smaller, brown cones that release pollen. Under optimal conditions, 'Skyrocket' Juniper can live for several decades, continuing to grow taller and producing cones annually. Over time, the plant may become woodier at the base with a thickened trunk and can eventually succumb to old age or environmental stresses.
- Propogation
Propogation time
Spring-Early Summer
Juniperus scopulorum 'Skyrocket', commonly known as Skyrocket Juniper, is best propagated through semi-hardwood cuttings. This method, usually performed in late summer to fall, involves taking 4 to 6 inch (10 to 15 cm) cuttings from the current year's growth that has started to mature but is not yet fully hardened. Before planting, the cut base of the cutting should be dipped in a rooting hormone powder to encourage root development. The cutting is then placed in a well-draining rooting medium, such as a mix of peat and perlite, ensuring high humidity and consistent moisture without waterlogging. Cuttings need to be placed in indirect light and can take several weeks to root successfully, after which they can be transplanted into individual pots or their final location.
