Formed Trees

At Nangle and Niesen we offer Box Head Trees and Pleached Trees expertly growing and training them to fit our client’s requirements.

Box head trees have a single stem with the crown trained on a frame and clipped to create a box/cubed head. Box head trees will provide structure and framework within a garden design and can be used as a specimen and are a great feature whether on their own or as part of a line or avenue.

Evergreen varieties will provide year-round screening while the bare branches of deciduous varieties provide interesting structure in the garden. A key feature is the ability to optimize screening while minimizing width taken up in the garden which is ideal where space is at a premium

Feel free to browse through our stock, we are always happy to talk about our trees. Visits to the nursery are welcome by appointment and are a great way to experience our trees for yourself.


  • "Acer campestre Elsrijk Pleached is a cultivar of the Field Maple and is named after the park in Amstelveen, Holland where it was discovered in the 1950s. It differs from the species in that it has a more regular, oval habit. Pleched. At Maturity one could mistake it for straight forward Acer campestre but one with a lovely compact shape. Acer campestre Elsrijk does best in rich, well drained soils, but does well in virtually any soil type, and will readily tolerate drought, soil compaction and air pollution. A medium sized tree which we particularly recommend for urban and street planting, its foliage turns a magnificent clear yellow in autumn."
  • "Acer platanoides Globosum was introduced in the 1870s. This lollipop tree is top grafted onto a platanoides stem to form a dense mop headed tree. A very good choice as a street tree and for urban plantings. It does well on most soil types, tolerates air pollution and resists drought. The dense rounded formality of the crown makes this a delight for architects seeking contrast. Wonderful when in full foliage, it is best for an urban environment where small is beautiful."
  • "Fagus sylvativa Atropurpurea (Copper Beech) root ball hedging in ready formed hedging elements for an instant Impact. Our hedging elements are grown in the field rather than in troughs. This makes them more versatile and means they can be planted together to create a screening effect or alone as a specimen adding structure and form within an overall garden design."
  • "Fagus sylvatica (Common Beech) root ball hedging in ready formed hedging elements for an instant Impact. Our hedging elements are grown in the field rather than in troughs. This makes them more versatile and means they can be planted together to create a screening effect or alone as a specimen adding structure and form within an overall garden design."
  • "Liquidambar styraciflua Gumball is a mop headed tree that retains its dwarfing round shape. Autumn colour is great, graduating to a deep claret in some years and the crop of 2015/16 retained this display thought the winter which was rather a surprise to us. Thriving on most well drained soils, stay clear of heavily alkaline soils. Often supplied as a half standard, this great autumn colour tree can be accommodated in most sized gardens."
  • "Prunus laurocerasus 'Novita' looks grand with its large, glossy foliage that stays put all year round. The glorious evergreen leaves are supplemented by scented white flowers that appear in spring. Later on, inedible, dark fruits appear. This is a particularly hardy evergreen laurel which makes a good hedging or screening plant, although the mature options we offer make a majestic specimen tree. Prunus laurocerasus 'Novita' is a vigorous tree, happiest in full sun or partial shade, but it can tolerate shade. Ideal for most soils except chalky."
  • "Grows from a shrub into a small to medium-size tree with a very dense branching and round crown to around 15 m but usually no more than about 10 m tall. The young twigs are conspicuously purple coloured which contrasts nicely with the dark green glossy leaf. The leaves are smaller and distinctly narrower than the species. This is the only way it differs from P. lusitanica. Thanks to the firm, leathery leaf, the tree is very wind resistant and can also tolerate sea wind. In 1893 it was described as a natural form (forma) of P. lusitanica. Suitable for use in parks and gardens, solitary or in groups. Needs protection against cold, drying wind."
  • "Taxus baccata, known as English Yew, is a versatile evergreen native tree that is often grown as a hedge. Incredibly long lived, it is often associated with churchyard planting and rejuvenates itself remarkably well if pruned hard in the early spring. It is worth noting that every part of Yew is poisonous, apart from the red flesh of the berry female plants produce, to humans and animals. It is a common misconception that the entire berry is poisonous however, that said, we would still not advise you to eat them! Like most evergreens it is not tolerant of waterlogged soils and thrives best on free draining lighter land."
  • Taxus baccata Fastigiata is a fastigiate or upright, slow-growing conifer with attractive, yellow tinted, evergreen foliage. Taxus baccata fastigiata has a fairly narrow width and columnar shape, making it ideal to use as sentries outside front doors and along pathways or to punctuate a border. This striking conifer is easy to maintain and stray stems can be trimmed back to maintain the symmetrical appearance. The foliage is highly toxic so take care around animals. Irish Yew is expected to reach a height and spread of 5 x 4 meters in 20 years, and will grow well in any situation, tolerating all soils, other than damp, badly drained conditions.
  • "Tilia platyphyllos is a fast growing tree which reaches significant heights and widths at maturity. It has luscious foliage which gives the tree a healthy appearance all year round. This tree has a roughly fissured bark which, unlike other Limes, tends not to sucker too much. The leaves are circular in shape and dark green. Like many Limes this tree has a lime yellow autumn colour and tends to lose its leaves early in the autumn period."
