Coastal Sites
Strong salt winds can provide difficult conditions for trees to grow in. Whilst it is unrealistic to expect to be able to grow an arboretum in such conditions, one can, through a combination of wind breaks and good species choice still grow an assortment of plants which will provide colour and interest. Listed below are a number of species that we grow on our nursery which are suitable for such conditions.
Ash - (Fraxinus excelsior) – Shallow rooted so can grow on poor quality soils.
Ash
Evergreen Oak - (Quercus ilex) – Also known as Holm Oak or Holly Oak. A large evergreen Oak native to parts of the mediterranean region. Grows to a height of between 20-30 metres and has leathery evergreen leaves which can withstand salt winds. The wood is hard and durable and historically used for pillars, wheels, barrells and as firewood. Does not like prolonged exposure to cold northerly winds. A prominent tree in the landscape due to its year round foliage.
Evergreen Oak
Hawthorn – (Crataegus monogyna) – A hardy shrub predominately grown as a hedge but if left will grow into a tree reaching a height of up to 14 metres.
Hawthorn/Quickthorn
Sweet Chestnut - (Castanea sativa) – Not native to Britain but considered a “Naturalised” species. Will grow into a large tree with deeply fissured often spiraling bark. The distinctive leaves are large and tough with serrated edges. Sweet chestnuts flower very late, often June into July and are distinctive in that trees have both male and female flowers on them which are pollinated by insects not the wind. Early growth is rapid and coppices well providing a good source of firewood.
White poplar - (Populus alba) – A medium sized tree growing to a height of between 15-30 metres. A decidious dioecious tree (seperate male and female trees). Requires abundant light and moisture and stands up well to flood water. Its extensive root system and ability to withstand salt winds makes it suitable for coastal planting. Can form extensive clonal colonies due to its ability to “sucker”.
