Not surprising but trees are also subject to the vagaries of the fashion trends, but as the market re-discovers old reliables, gardeners are also being more adventurous and new alternatives are also becoming very popular: Malus 'Evereste' (ornamental crab apple) is a conical tree with lobed leaves and ideal specimen for small gardens.
Malus is one of the best for early spring blossom with eye-catching red buds and fantastic autumnal fruit.
Olive 'Europea' when it comes to selecting a stunning evergreen specimen, the olive tree with its silvery green foliage and rugged stems are certainly a very popular choice.
Slow growing and easy to maintain looks great in a row or as a specimen.
Crataegus laevigata 'Paul's Scarlet' (Hawthorn) offers a very interesting spring and autumn colour.
A popular deciduous tree with red blooms in May and deep red berries in autumn.
Betula jacquemontii (Himalayan Birch) a very popular deciduous tree with architects is increasingly winning favour with gardeners for its striking peeling white bark scored with dark lines.
Unlike the common Silver Birch (Betula Pendula) the leaves of the Betula Himalayan are oval turning golden yellow in autumn.
Great planted in a row or for added interest as a specimen look out for a multi-stem.
Sorbus acuparia 'Autumn Spire' is a relatively new variety of Mountain Ash, boasting an extraordinary compact and upright growth habit.
The popular columnar tree has fantastic fine cut foliage and glossy yellow berries with red tinge making it an ideal choice for growing in a row to provide a dappled screen.
Excellent red coloured foliage in Autumn can provide added interest in the planted border.
