If you are seeking an attractive array of blossom, species of crab apple, cherry, magnolia and hawthorn are popular choices. However, there are a whole host of trees that produce striking foliage. You might want to think about what colour ‘palette’ you would like, as foliage shades can range from warm, sunny yellows and vibrant reds to cool greys and silvers.
Some trees, like the Japanese acer and liquidambar, are fabulous for autumn colour. Others, such as some species of maple and horse chestnut, produce wonderful pink blossom in spring. To achieve all-year-round colour, go for evergreen trees like cedar, fir, cypress or photinia.
If you would like to add another dimension to the visual interest of your trees, you might want to bear in mind species that have distinctive bark. This includes species such as ornamental pear, Paul’s Scarlet hawthorn, the paper bark birch or cherry, or the snakebark maple.
