Western red cedar


Description Thuja plicata 'Kager's Beauty' | Western red cedar

Kager's Beauty western red cedar is a distinctive cultivar of Thuja plicata with green, evergreen foliage and an unusual outline. Its compact, bushy growth is irregular rather than formally shaped, and the twisted shoots give it character throughout the year. This is a coniferous shrub, not a tall tree form. It reaches an approximate mature height of 150 cm; no mature width is specified, so allow for its natural bushy habit without relying on an estimated spread. The evergreen foliage keeps a green presence in the garden beyond the flowering season, although flowering details are not available. Slow growth means changes in size are gradual, but it does not remove the need to choose a position with room for the plant’s eventual height and outline. Western red cedar is the UK common name, while giant arborvitae is another name sometimes used for the group. This cultivar is a compact choice for gardeners who want a conifer with a less regular form than a standard upright specimen. It belongs to the Thuja genus, which helps identify it among other conifers. Its twisted shoots and bushy shape are the defining features to consider when deciding whether its appearance will suit a particular garden position.

Key features of western red cedar (Thuja plicata 'Kager's Beauty')

  • The foliage is green and evergreen, giving the plant a lasting presence in the garden. Its distinctive twisted shoots set it apart from a conifer with a more regular outline. Individual leaf shape is not specified.
  • Its growth is slow, and the overall habit is compact, bushy and irregular. The approximate mature height is 150 cm. No mature width is supplied, so the plant’s eventual spread should not be assumed from its height.
  • Choose a position in sun or partial shade. These options suit a range of UK garden settings, but the plant’s soil needs remain important wherever it is placed.
  • It prefers humus-rich soil that stays slightly moist while remaining well drained. Prolonged drought is poorly tolerated, so it is not a suitable choice where the soil is likely to remain dry for long periods.

Uses of Kager's Beauty western red cedar in the garden

  • Use it as a specimen where its compact, bushy and irregular outline can be seen clearly. The twisted shoots provide the main point of interest, while the green evergreen foliage gives the plant structure through the year.
  • It can also be used in a rock garden or in group planting. In a group, its particular shape can contribute contrast, while a rock garden offers a setting for a compact conifer; choose a position that still provides sun or partial shade and suitable soil.
  • A container is another stated use. Its approximate mature height of 150 cm and slow growth are useful points to consider when choosing where a potted plant will sit. Make sure the chosen position can meet its preference for slightly moist, well-drained, humus-rich soil.
  • The supplied hardiness range is -28.9°C to -23.3°C, corresponding to USDA zone 5. This is a USDA rating, not a UK-specific guarantee, so it should not be taken as a promise of performance in every UK garden or location.
  • For a planting combination, consider other plants suited to sun or partial shade and slightly moist, well-drained soil. No particular companion plants are specified, so choose them according to the conditions they share rather than relying on a named planting scheme.

As one of the conifers, this cultivar can add year-round structure to a suitable garden position through its compact evergreen presence and distinctive twisted shoots.

Planting & care Thuja plicata 'Kager's Beauty' (Western red cedar)

We would like to provide some tips on how to plant and care for a Thuja plicata 'Kager's Beauty'. By following these tips, you can be sure to enjoy your Western red cedar for a long time.

Ideal placement of a Thuja plicata 'Kager's Beauty' (Western red cedar)

Choose a sunny or partially shaded position; good light helps maintain dense growth. It grows best in fertile, humus-rich soil that retains some moisture but drains freely. Avoid waterlogged ground and, where possible, sites exposed to drying winds.

How do I plant a Thuja plicata 'Kager's Beauty' (Western red cedar)?

Plant during a mild spell in autumn or spring, when the soil is workable and not waterlogged or frozen. Dig a hole slightly wider than the root ball and set the plant at the same depth as it was growing in its pot. Backfill with the excavated soil, firm gently and water thoroughly; keep the soil moist while the plant establishes.

Pruning a Thuja plicata 'Kager's Beauty' (Western red cedar)

This compact cultivar generally needs little pruning beyond removing dead or damaged growth. If shaping is needed, trim lightly in late spring or summer, cutting only into green, leafy growth. Avoid cutting back into bare old wood, as it may not produce new shoots.

Watering a Thuja plicata 'Kager's Beauty' (Western red cedar)

Water thoroughly after planting and keep the root area evenly moist during the first growing season, especially in dry weather. Established plants usually need watering only during prolonged dry spells, but check soil moisture rather than relying on a fixed schedule. Container-grown plants dry out faster and need more frequent checks; avoid leaving roots in waterlogged soil.

Fertilising a Thuja plicata 'Kager's Beauty' (Western red cedar)

In spring, apply a modest amount of general-purpose fertiliser or a balanced, slow-release feed around the root area, following the product instructions. A mulch of well-rotted organic matter can help improve the soil and retain moisture. Avoid excessive feeding, particularly with high-nitrogen fertilisers, as this can encourage soft growth.

The characteristics of a Thuja plicata 'Kager's Beauty' (Western red cedar)

Thuja plicata 'Kager's Beauty' is a compact, evergreen conifer with a naturally rounded, dense habit, making it useful for small gardens, mixed borders and year-round structure. Its foliage is scale-like and aromatic when crushed, while its small cones are not its main ornamental feature. Like other western red cedars, it can suffer if the roots are allowed to dry out for long periods or remain in poorly drained soil.

Separating/dividing a Thuja plicata 'Kager's Beauty' (Western red cedar)

Dividing is not suitable for this woody conifer. It is normally maintained by light pruning rather than splitting, and specialist propagation is usually by semi-ripe cuttings. For a garden plant, buy a nursery-grown specimen rather than attempting division.

Frequently Asked Questions Thuja plicata 'Kager's Beauty' (Western red cedar)

What will be the height of Thuja plicata 'Kager's Beauty'?

It is a compact cultivar and is generally much smaller than the species, but its eventual height depends on growing conditions and how it is maintained. Allow room for a small, rounded evergreen shrub rather than expecting it to remain permanently tiny.

What will be the width of Thuja plicata 'Kager's Beauty'?

It develops a rounded, spreading outline, with its eventual width varying according to age and growing conditions. Allow space around it, or prune lightly while it is still within the green foliage.

Which soil type is most suitable for the Thuja plicata 'Kager's Beauty'?

It prefers fertile, humus-rich soil that retains some moisture but drains well. Avoid persistently waterlogged ground, and do not let the root area become very dry for extended periods.

What is the ideal positioning for the Thuja plicata 'Kager's Beauty'?

A sunny or partially shaded position is suitable, ideally with shelter from drying winds. Good light and moist, well-drained soil help it grow evenly.

What is the flowering colour of the Thuja plicata 'Kager's Beauty'?

It does not produce showy ornamental flowers. Its garden interest comes mainly from its evergreen foliage and compact shape.

What is the flowering time of the Thuja plicata 'Kager's Beauty'?

Flowering is not a notable ornamental feature, so it is not usually grown for a particular flowering season. Its evergreen foliage provides interest throughout the year.

Is the Thuja plicata 'Kager's Beauty' hardy?

It is generally hardy in the UK when planted in suitable, well-drained soil. Newly planted specimens and plants in containers can be more vulnerable to severe cold and drying winter winds.

Is the Thuja plicata 'Kager's Beauty' evergreen?

Yes, it is an evergreen conifer and retains its foliage throughout the year. Some foliage may naturally shed or discolour as it ages.

What is the growth strength of the Thuja plicata 'Kager's Beauty'?

It is a compact cultivar and is generally slower-growing and less vigorous than the species. Its pace and final size vary with soil, light and growing conditions.

What kind of bark does the Thuja plicata 'Kager's Beauty' have?

It has woody stems with brown bark, but the plant's compact habit means the bark is not usually a prominent ornamental feature. Its foliage and rounded outline are more noticeable.

Is Thuja plicata 'Kager's Beauty' poisonous?

Warning: This plant may contain toxic substances. Ingestion of any part of the plant or contact with its sap may pose health risks, particularly to children and pets such as cats and dogs. We recommend keeping the plant out of reach of children and animals and wearing protective gloves when carrying out maintenance work, such as pruning or transplanting. If poisoning is suspected, seek immediate medical or veterinary advice. This information is provided as a general safety notice.

Its compact habit makes it more suitable for container growing than many larger conifers, provided the pot is generously sized and has good drainage. Container plants need more regular watering and feeding than those in the ground, and may benefit from protection around the roots during severe winter weather.
