This cultivar of Chinese juniper forms a spreading, dense mound, providing excellent texture contrast in landscapes where year-round structure is needed. Its evergreen nature ensures visual appeal even during the dormant winter months.

This hybrid juniper exhibits excellent adaptability, performing reliably across USDA hardiness zones 4 through 9. It is a moderately sized shrub that naturally matures into a wide-spreading form, making it ideal for softening hard lines in foundation plantings or serving as a durable ground cover. Gardeners value the Juniperus × pfitzeriana ‘Mint Julep’ for its robust constitution and minimal care requirements once established.

How to Grow

For optimal growth, plant Juniperus × pfitzeriana ‘Mint Julep’ during the spring or fall when temperatures are moderate. Locate it where it will receive full sun exposure, as inadequate light can thin the foliage. This Chinese juniper is highly adaptable regarding soil type, thriving in average, well-drained media, though it also tolerates clay soils well. Critically, ensure the planting site avoids perpetually wet or poorly drained areas, as this species is intolerant of wet soils and prone to root rot there.

Watering should be consistent and medium in volume, especially during the first year as the root system establishes itself. Once mature, this juniper shows good drought tolerance, requiring deep watering only during prolonged dry periods. Fertilization is rarely necessary, making this a truly low-maintenance choice.

Pruning, if performed, should aim to maintain the naturally spreading habit rather than forcing an unnatural shape. If shaping is desired, light trimming of the branch tips in early spring can help keep the habit compact. This plant is particularly valued for its urban tolerance, handling many city air pollutants efficiently.

Landscape Uses

The versatile shape and size of Juniperus × pfitzeriana ‘Mint Julep’ make it suitable for numerous landscape roles. It excels as a formal or informal low hedge where its dense, spreading form effectively screens or borders spaces. For rock gardens or along difficult slopes, its hardiness and drought tolerance combine with its ability to manage erosion make it an excellent structural plant.

This spreading ground cover shrub is perfect for mass plantings where uniformity and low upkeep are priorities. Consider placing it near foundations where its mounding shape can soften hard architectural lines without growing too tall. While it covers ground effectively, this Chinese juniper rarely requires companions due to its excellent landscape presence, though low-growing perennials that enjoy full sun and sharp drainage can provide seasonal contrast beneath its canopy.

Standout Features

Noteworthy Characteristics

Juniperus × pfitzeriana is a hybrid designation that includes certain cultivars that are crosses between J. Chinensis and J. Sabina. Such cultivars in the Pfitzer Group are sometimes commonly called pfitzer juniper. The cultivar ‘Mint Julep’ is a compact, spreading, evergreen shrub that typically grows 4-5’ tall and 4-8’ wide over the first 10 years, noted for its mint green foliage that retains good color through winter. Although sometimes sold confusingly under J. chinensis, ‘Mint Julep’ is very similar in appearance to ‘Sea Green’.

Tolerances

• Deer
• Drought
• Erosion
• Dry Soil
• Shallow-Rocky Soil
• Air Pollution

Potential Problems

Junipers generally carry susceptibility to several fungal issues common to the genus. Tip and needle blights can affect the foliage, often exacerbated by poor air circulation or overly wet conditions. Gardeners must also watch for cedar-apple rust and related rust diseases, which use junipers as a required alternate host during part of their life cycle.

In terms of insect pests, while generally robust, occasional infestations by aphids, bagworms, webworms, and scale may occur; regular scouting will allow for early treatment. The most significant cultural problem to avoid is root rot, which develops strictly in wet, poorly drained heavy soils—a crucial reason to select well-drained sites for planting the Juniperus × pfitzeriana ‘Mint Julep’.
