Carpinus betulus 'Fastigiata' (Upright Hornbeam)

Carpinus betulus 'Fastigiata', commonly known as Upright Hornbeam, is a deciduous tree prized for its distinctive columnar growth habit and dense foliage. This variety is highly valued for its ornamental beauty, making it an excellent choice for urban landscapes, parks, and large gardens.

Height and Width

• Height: Typically grows to a height of 10 to 15 meters.
• Width: Forms a narrow columnar shape with a spread of about 3 to 5 meters.

Soil Type

• Soil Preference: Carpinus betulus 'Fastigiata' prefers well-drained soil with a loamy or sandy texture. It can tolerate a range of soil pH levels, from slightly acidic to slightly alkaline. This tree is adaptable to various soil types but thrives in moist, fertile soil.

Plant Description

• Foliage: The tree features dense, dark green foliage that turns a vibrant yellow-orange in autumn before dropping in winter. The leaves are serrated and ovate in shape, adding texture and visual interest to the landscape.
• Growth Habit: Carpinus betulus 'Fastigiata' has a narrow, columnar growth habit, with branches ascending upwards in a tight, upright form. This makes it an ideal choice for narrow spaces or as a vertical accent in the landscape.

Flower Description

• Flowers: In spring, Upright Hornbeam produces inconspicuous, greenish-yellow flowers that are not particularly showy but are attractive to pollinators such as bees and butterflies.

Fruit Description

• Fruit: Following the flowers, this tree produces small, winged nutlets arranged in clusters, known as samaras. These nutlets are not ornamentally significant but may attract birds and wildlife.

Cultivation and Care

• Watering: Carpinus betulus 'Fastigiata' prefers regular watering, particularly during periods of drought or dry weather. It is important to keep the soil consistently moist, especially during the tree's establishment period.
• Sunlight: Prefers full sun to partial shade. While it can tolerate some shade, full sun exposure is ideal for promoting dense foliage and vigorous growth.
• Pruning: Prune as needed to maintain the tree's desired shape and remove any dead, damaged, or crossing branches. Avoid heavy pruning, as this can disrupt the tree's natural form and structure.
• Fertilising: Generally, this tree does not require heavy fertilisation. A balanced fertiliser applied in spring can help promote healthy growth and foliage.

Additional Notes

• Pests and Diseases: Carpinus betulus 'Fastigiata' is relatively resistant to pests and diseases, particularly when grown in well-drained soil and provided with proper care. However, it may occasionally be susceptible to aphids, caterpillars, or fungal diseases such as powdery mildew.
• Uses: Ideal for use as a specimen tree, vertical accent, or screen in urban landscapes, parks, or large gardens. Its narrow, upright growth habit makes it particularly well-suited for narrow spaces or as a formal hedge or boundary planting.
