The Pimoko Serbian Spruce (Picea omorika ‘Pimoko’) is a distinctive, compact evergreen conifer, desirable for gardeners. Its small stature offers a compelling alternative to larger evergreens. This dwarf variety provides year-round interest, fitting well into various garden styles without demanding extensive space. It is an excellent choice for gardeners seeking a low-maintenance, visually appealing plant.
Defining Characteristics
The Pimoko Serbian Spruce is a compact, slow-growing conifer, typically forming a globe-like or broadly rounded shape. While young plants often maintain a neat, globular form, they can develop multiple leaders and broaden with maturity. Its growth rate is notably slow, generally adding only 1 to 6 inches per year. After about 10 years, it might reach approximately 1 to 2 feet tall and 2 to 4 feet wide, with some sources suggesting a mature size of up to 18 inches tall and 30 inches wide.
Its unique needle coloration is a defining feature. The short, dense needles are dark green on their upper surfaces, while their undersides boast a striking silvery-blue or white appearance. This contrast creates a shimmering or sparkling effect, particularly when viewed from different angles or in a breeze. Reddish-brown buds provide additional visual interest against the foliage.
Optimal Growing Conditions
The Pimoko Serbian Spruce performs best when planted in full sun, though it can tolerate partial shade. Adequate sunlight (ideally more than six hours daily) contributes to optimal growth, though prolonged exposure to intense direct sun should be avoided in warmer climates to prevent needle scorch.
This spruce prefers moist, well-draining, and loamy conditions. It is adaptable to various soil types, including slightly acidic to neutral pH levels, typically ranging from 5.0 to 7.4. Proper drainage is important, as the plant does not tolerate standing water. The Pimoko Serbian Spruce is hardy in USDA Zones 4 through 8. It is also notably deer and rabbit resistant.
Planting and Cultivation
Dig a planting hole that is as deep as the root ball and two to three times as wide. Mixing the excavated soil with compost or peat moss can improve soil structure and enrich it.
Carefully remove the plant from its container, gently loosening any tightly packed roots. Position the plant in the hole so that the top of the root ball is level with or slightly above the surrounding soil line, ensuring the base of the trunk remains exposed. Backfill the hole, firming the soil around the root ball to eliminate air pockets, and then water thoroughly. Applying a 2-inch layer of mulch around the planting area helps retain soil moisture and regulate temperature, but keep it a few inches away from the trunk.
For newly planted spruces, consistent watering is important to establish a robust root system. During the first growing season, water deeply two to three times per week, allowing the top 2 inches of soil to dry slightly between waterings. Once established, the Pimoko Serbian Spruce becomes more drought-tolerant, often only requiring supplemental watering during extended dry periods. Fertilization is generally not heavily required, but a general-purpose fertilizer can be applied in spring before new growth begins. Pruning is minimal, primarily for removing any dead or damaged branches, as the plant naturally maintains its compact form.
Design and Landscape Uses
The Pimoko Serbian Spruce is highly versatile for various landscape applications. Its small size makes it an excellent choice for confined spaces and rock gardens, where its unique texture and color can be highlighted.
This dwarf spruce also performs well in containers for placement on patios, balconies, or as an accent near entryways. It can be effectively used in borders, as edging, or as a small-scale groundcover due to its low, mounding habit. Its year-round evergreen foliage and distinctive color provide consistent visual interest, making it a valuable addition to mixed perennial beds or as a specimen plant.
