Skyrocket Juniper
Juniperus scopulorum 'Skyrocket'
Skyrocket Juniper is grown for its foliage rather than flowers, giving the garden structure and color all season long.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Skyrocket Juniper
Plant it in full sun. It prefers low water. It is hardy in USDA zones 3–9. Expect it to reach about 16 ft tall and 2 ft wide at maturity, in roughly 12 years (not yet checked).
What was checked
Mature height and spread, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not, and each fact above says which. The planting, spacing and size sections are derived from these checked facts by a fixed rule, not checked separately, and the plant type is the library's own classification.
When to plant Skyrocket Juniper
Plant Skyrocket Juniper in spring once the soil is workable, or by very early fall at the latest: an evergreen needs its roots down well before the ground freezes. In zone 6, the middle of its hardy zones 3 to 9, that is March to May, or August on the fall side.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 6, the middle of this plant's hardy range, start with zone 6 in March. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Skyrocket Juniper
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Skyrocket Juniper about 2 ft apart, center to center, so each plant has room to reach its full width.
Add Skyrocket Juniper to a garden plan and the planner draws it at its full width, so you see the spacing before you buy.
Where these facts come from
Skyrocket Juniper's height, spread, hardiness zones, sun and trait tags were checked against 12 published sources on July 31, 2026. Each one is linked below with every fact it carried, which can include a fact this page still marks as not yet checked, because a source carrying a value is not the same as the value being held to the standard. Facts not in that list, and the planting, spacing and size sections, are not covered by these sources.

Safety
Toxicity depends on the species. Savin (Juniperus sabina) is dangerous: its oil can cause miscarriage and liver damage. Common junipers show no such effect. Never use juniper oil internally. per Molecules
