Why Choose Thuja occidentalis Varieties?

Thuja occidentalis varieties are prized for their classic good looks and versatility. Their tidy, upright growth makes them excellent for creating formal hedges or screens, while more compact cultivars are ideal for small gardens or container planting. Many varieties feature unique foliage colours, from fresh emerald greens to gold-tipped new growth, offering year-round interest. These hardy evergreens are also relatively low maintenance, tolerating a range of soils and thriving in full sun to partial shade.

Popular Thuja occidentalis Varieties

'Rheingold'

Thuja occidentalis 'Rheingold' is a standout among Thuja occidentalis varieties, famous for its golden-yellow spring foliage that matures to rich coppery tones in winter. With its naturally conical shape and compact size, it's perfect for border accents or low hedges. The soft, feathery foliage also makes it popular in mixed shrub plantings.

'Caespitosa'

For gardeners seeking a low, spreading form, Thuja occidentalis Caespitosa offers a delightful solution. This dwarf cultivar forms neat, rounded mounds of bright green foliage, ideal for rockeries, pathway edging, or container displays. Its manageable size and tidy habit make it easy to incorporate into any garden design.

'Smaragd' (Green Cedar)

For a classic, elegant hedge, Thuja occidentalis 'Smaragd' (Green Cedar) is a top choice among Thuja occidentalis varieties. Its naturally narrow, upright shape and vivid emerald-green colour provide year-round privacy and structure with very little trimming required. It’s especially effective as a living screen or feature column in formal or contemporary settings.

'Holmstrup'

Thuja occidentalis Holmstrup is ideal for those who want a compact, slow-growing variety with dense, rich green foliage. It maintains a neat, upright form, making it a great option for smaller hedges and foundation plantings. Its tidy growth habit also lends itself well to topiary or clipped shapes.

Among the most stately Thuja occidentalis varieties, Thuja occidentalis 'Pyramidalis' features a slender, columnar shape perfect for creating architectural accents in the landscape.

Growing and Caring for Thuja occidentalis Varieties

Most Thuja occidentalis varieties thrive with regular watering during establishment, followed by minimal care once mature. They prefer well-drained soils and benefit from a layer of mulch to retain moisture and regulate root temperature. Although generally tolerant of pruning, most cultivars naturally maintain their shape, needing only light trimming if desired.
