Description
Thuja occidentalis 'Smaragd' standard | Western red cedar 'Smaragd' standard
The Smaragd arborvitae standard is Thuja occidentalis 'Smaragd' supplied in a distinctive standard form. The cultivar name is 'Smaragd'. A stem carries its compact, dense, conical crown above the ground, giving the plant a clear outline that differs from the same cultivar grown as a shrub or hedge plant. Its green foliage is evergreen, and it usually retains its green colour through winter. This gives the standard a defined presence throughout the year, rather than a seasonal display based on flowers. Fruit-bearing is indicated, but no details about the fruit are available. The product information does not give mature height or width, so these are not specified here. The raised crown is the key feature to consider when choosing this plant: it brings the evergreen form up on a stem and creates a compact focal point in a garden position or container. For shoppers comparing forms of Thuja, this is the standard, rather than a hedge-grown plant or a shrub form of the cultivar.
Key features of Thuja occidentalis 'Smaragd' in standard form
- Evergreen foliage: The foliage is green and evergreen, with the plant usually retaining its green colour in winter. This provides a consistent foliage feature through the year. No leaf shape or flowering details are specified.
- Raised, conical crown: The plant is supplied as a standard, with a stem supporting a compact, dense, conical crown. This raised structure gives it a different outline from the same cultivar grown as a shrub or hedge plant.
- Aspect and soil: Choose a position in full sun or partial shade. The plant prefers well-drained, humus-rich soil that remains lightly moist. Good drainage matters in UK gardens, where wet conditions can leave soil waterlogged.
- Moisture balance: The preferred soil should not remain waterlogged, and prolonged drought should also be avoided. These points help describe the conditions suited to this Smaragd standard without assuming a particular soil pH or site tolerance.
Uses for a Smaragd arborvitae standard in the garden
- Specimen planting: Use the standard as a specimen in a suitable garden position. Its stem lifts the compact crown above the ground, making the conical outline easy to distinguish from a shrub or hedge-grown plant.
- Pots and terraces: This form is suited to a pot on a terrace or by an entrance. The raised crown gives the planting a defined focal point, while its compact form keeps the visual emphasis on the plant itself.
- Hardiness: The supplied hardiness is USDA zone 4, corresponding to an approximate temperature range of -34.4°C to -28.9°C. This is a guide to the stated hardiness; local site conditions can still affect how a plant performs.
The evergreen foliage, dense growth and raised conical crown give this plant its ornamental value. It can bring a compact focal point to a pot, terrace, entrance or suitable garden position. For related choices, browse evergreen shrubs.
