Description
Microbiota decussata Shrub | Russian cypress
Russian cypress shrub, known botanically as Microbiota decussata, is a spreading, trailing and bushy conifer offered in shrub form rather than as a tree. It develops a broad, low-to-medium-height silhouette and reaches approximately 80 cm in height at maturity. This makes it useful where evergreen, spreading cover is wanted without the upright shape of a tree or standard. The aromatic foliage stays green through the year, with bronze colouring adding seasonal interest. Flowering is inconspicuous and is not the main ornamental feature of this plant. As an evergreen conifer, the shrub gives borders, slopes and planting groups a steady structure in every season. It is also low maintenance, which suits gardeners looking for a hardy ground-covering plant with limited care needs. In wet UK conditions, good drainage is important, as persistently waterlogged soil does not suit this shrub. Russian cypress is also called Siberian cypress, and its compact height and bushy spread make it distinct from taller cypress forms. Its place among conifers reflects its evergreen character and useful garden structure.
Key features of Russian cypress (Microbiota decussata)
- Foliage: The aromatic foliage is evergreen and green, with bronze colouring that adds a changing seasonal tone. The foliage is valued for its year-round presence rather than for showy flowers.
- Flowering: Inconspicuous flowers appear in April and May. They are not the main ornamental feature, so the shrub’s value comes mainly from its evergreen cover, spreading habit and foliage colour.
- Aspect and soil: Choose full sun or partial shade. A well-drained, humus-rich soil is preferred, with a slightly acidic to neutral pH. Good drainage and an open soil structure are especially important in gardens with wet winter conditions.
- Growth and form: This shrub form grows as a spreading, trailing and bushy evergreen plant. It reaches approximately 80 cm in height and creates a broad, low-to-medium-height presence for ground-covering planting. It is useful as a evergreen ground cover where a low, spreading shape is wanted instead of an upright tree.
Uses of Russian cypress shrub in the garden
- Ground cover and planting groups: The spreading shrub form works well as evergreen ground cover in borders, group planting and wider planting schemes. Its broad silhouette helps give low areas a consistent structure without creating an upright tree shape.
- Rock gardens and slopes: Russian cypress shrub is suitable for rock gardens and slopes where a hardy, trailing plant can provide low-to-medium-height cover. Its evergreen foliage keeps these areas visually structured beyond the flowering season.
- Hardiness: This is an exceptionally hardy plant, tolerating approximately -40°C and corresponding to USDA zone 2. It is therefore suited to gardeners seeking a very hardy Russian cypress for a well-drained position.
- Plant combinations: Combine it with other hardy plants that prefer well-drained soil. Hardy border plants, rock-garden plants, evergreen ground-cover plants and other low-maintenance conifers can contrast with or complement its green foliage and bronze seasonal colouring.
- Ornamental value: The main appeal is the year-round evergreen structure, aromatic foliage, spreading shrub silhouette and bronze tones. This gives planting schemes a stable base while keeping the overall profile low and broad.
Russian cypress shrub is particularly useful where a very hardy, evergreen and spreading ground-covering structure is wanted in well-drained soil.
