Juniperus chinensis ‘Shimpaku’, commonly known as Shimpaku Juniper, is one of the most respected and widely grown Chinese junipers in cultivation. Valued for its refined foliage, rugged character, and long-term durability, Shimpaku is equally suited for bonsai training and landscape use, making it one of the most versatile evergreen conifers available. At Maple Ridge Nursery, Shimpaku is grown for strong root systems, balanced branching, and reliable performance across a wide range of climates. Growth Habit & Mature Size Shimpaku Juniper is a slow to moderate growing evergreen with a naturally irregular, layered habit. When planted in the landscape, it typically matures to 4 to 6 feet tall and wide, though size and form can be easily managed through pruning. Its flexible branching structure allows it to be shaped, trained, or maintained naturally, making it suitable for both formal garden designs and informal plantings. Foliage Characteristics Shimpaku features fine, scale-like foliage with a dense, compact texture and deep green color that holds year-round. Unlike many other junipers, established plants produce very little sharp juvenile growth, resulting in a softer appearance that is ideal for close viewing and detailed shaping. Bark & Seasonal Interest As it matures, Shimpaku develops naturally exfoliating bark, revealing layered tones of gray, tan, and reddish brown. This peeling bark adds age and character over time, enhancing its value as a specimen plant and contributing to its reputation as a premier bonsai variety. Sun, Soil & Water Requirements Sun Tolerance: Partial Sun Soil: Well-drained soil is essential Water: Moderate water; drought tolerant once established Shimpaku Juniper performs best in partial sun and in soils that drain freely. Shimpaku should never be planted in areas where water remains standing for extended periods. Cold Hardiness & Reliability Shimpaku is cold hardy to USDA Zone 5 and highly tolerant of heat, wind, and dry conditions. Once established, it is a low-maintenance evergreen with strong resistance to common juniper pests and diseases when grown in proper conditions. Landscape & Bonsai Uses Shimpaku is commonly used as premier bonsai material. It can be used as an accent plant in Japanese inspired gardens. Shimpaku is a good option for rock gardens, slopes, and raised beds. Shimpaku is a specimen evergreen great for year-round interest. Why Choose Shimpaku Juniper from Maple Ridge Nursery?
