Botanical Name Acer campestre


Common Name Common Maple


Description


The native Common or Field Maple is a variable tree of medium height thriving in sun or shade. The head is rounded, broad and informal. The lobed deciduous leaves open tinged-red turning bright yellow in autumn. Yellow-green flowers in small loose clusters are produced in April followed by winged fruit called 'keys' which mature from green to brown, possibly red-tinged, August-September. Grows to a height of 8-12m with a 10-12m spread.


Acer pseudoplatanus


Sycamore


Naturalized in Britain for centuries, the Sycamore is a very variable spreading tree, often rounded though, tolerant of wind, salt, atmospheric pollution and poor soil. Large, usually five-lobed deciduous foliage sometimes shows good yellow shades in autumn. Produces abundant light green seed with wings sometimes tinged pinky-red before aging to brown. Grows to a height of 25-30m with a 20-25m spread.


Health & Safety and Care Notes Health & Safety Note


Tolerant of pollution, road salt and lime. Young plants respond well to trimming and so makes a good hedge.


Risk Rating

Self-sown seedlings can prove troublesome weeds. Clonal selections are better behaved. Aphids gather on flower stalks & under-sides of leaves


Alnus cordata


Italian Alder


The Italian Alder is a large, fast growing, wind tolerant tree, which does well in a wide range of soils, including moist, even wet ground. Its crown has a narrow, conical, almost columnar form that can be somewhat irregular. The glossy heart-shaped foliage appears early in spring and persists until the frosts with some leaves briefly turning yellow though not a distinctive characteristic. Grows to a height of 15-20m with a 6m spread.


Relatively brittle branches are easily damaged in transport. Although grows in moist ground conditions, will require adequate drainage on planting in order to enable successful establishment. Being susceptible to Phytophthora root rot avoid locations liable to flood, specifically along the banks of slow moving water courses.


Alnus glutinosa Common Alder


The Common Alder is a densely branched, medium-sized, occasionally taller tree. Rounded foliage follows the yellow catkins in March. Excellent on moist, even wet sites. Good wind tolerance. Grows to a height of 15- 20m with an 8-10m spread.


Relatively brittle branches are easily damaged in transport. Although grows in moist ground conditions, will require adequate drainage on planting in order to enable successful establishment. Being susceptible to Phytophthora root rot avoid locations liable to flood, specifically along the banks of slow moving water courses.


Betula pubescens Downy Birch


The Downy or White Birch, like pendula, is a native but the basal bark on the trunk is white or grey rather than black, the foliage slightly more rounded and the shoots less pendulous giving an upright although shorter form. Usually does better on moist soils. Grows to a height of 15-20m with a 6-8m spread.


Root-ball recommended from 12- 14cm girth and upwards. Although grows in moist ground conditions, will require adequate drainage on planting in order to enable successful establishment.


Carpinus betulus


Common Hornbeam


The hornbeam is a shade tolerant, relatively slow growing but ultimately tall tree. The trunk has smooth grey bark which often has prominent ribs. The foliage is ovate and toothed with an uneven surface. When used as a hedge, the brown autumn foliage which rustles in the wind, persists all through the winter. Grows to a height of 15-20m with a 12-15m spread.


Best in well drained, fairly rich conditions, but can thrive in chalky, sandy or dry soil. Root-ball recommended from 12-14cm girth and upwards. Not for very windy locations. Responds well to trimming and so makes a good hedge with cost effective instant hedging being achieved by using 200-250 or even 175-200cm high feathered plants immediately cut back upon planting to promote bushiness down to the ground.
