There is a Huge range of Trees,in all shapes and sizes,for gardens large and small,flamboyant and subdued.Evergreen or deciduous,trees are the best way of injecting height,shape and of structure,summer shades and long winter shadows.The most rewarding provide colored bark,flowers,fruits,flashy autumn leaves,and a tracery of winter stems.
Trees are a key part of garden design.They can denote a boundary,signal the entrance to a completely different part of the garden,or act as the focal point within a specific area,encapsulating its style and mood.
A tree is a long-term investment.Before buying,check its final size,and its site and soil requirements,to make sure that it will flourish.
Several trees kick off the spring with a superb aerial mass of blossoms.The ornamental cherries offer a lively choice,especially Prunus sargentii(Sargent Cherry),which gives a terrific show of pale pink flowers against red leaves.
But if that’s’s too tall for your garden,Try Amelanchier x grandiflora’Ballerina’ with its beautiful clusters of white blossoms,or the weeping Malus x scheideckeri ‘Red jade’,which gives an outburst of frothy white flowers.
Other stunning spring choices include the flowering mgnolias;the best selection of these trees is available through specialist catalogs.
Trees in Summer add leafiness,shade,shape and color.Most of the non-green kinds are in the purple-bronze range,such as the copper or purple beech(Fagus sylvatica’Dawyck Purple’),but you can be much bolder with Populus x Canadensis which has bright golden yellow leaves,or a conifer with beautiful blue-tinged growth.the forms of trees and the shade they cast vary,some providing a massive,chunky canopy,others contributing slim and stylish verticals that keep the eye moving.Juniperus communis’Hibernica’ is like a giant evergreen pencil,upto 15ft(5m) high and as wide as a dinner plate.
For oriental gardens there’s the populr,pyramidal Chamaecyparis obtuse(Nana Gracilis),and for formal gardens the tiered branches of Cornus controversa”Variegated”.If you need trees that will let in more light,don’t be afraid to have some pruning and sawing done to create a better shape.
Autumn and Winter:
The autumn show is one of the great sights of the gardening year,especially in the Northeast,and every garden needs at least one tree whose leaves do a quick color change,then fall,going out with a bang.Sweetgums,Japanese mples,and tupelos all give an excellent show of autumn foliage.As a bonus,the falling leaves of Cercidiphyllum japonicum(Katsura tree)emit ascent of caramel apples.
The best winter trees have a tracery of branches or brightly colored bark.Bark colors range from the shiny copper brown of Prunus serrula(ornamentl cherry) to the bright whites of the birches;plant them against a contrasting background to maximize their effect.Other great winter trees include Acer rufinerve,with its green-and-white-striped branches,hollies for their blood-red-berries and above all,the evergreen Eriobotrya japonica(loquat) for its magnificient,leathery,tactile leaves,upto 12in(30cm) long.
