A Blaze Of Autumn Colour

Autumn is a time of glorious colour in the garden with fiery shades of foliage that seem to glint in the sunlight.  As the season changes the chlorophyll that gives leaves their green colour begins to break down turning the foliage to magnificent shades of orange, yellow red or purple.  It’s not just trees that can provide spectacular autumn colours - some shrubs are still flowering at this time of the year and fruiting shrubs produce berries which the birds love.  Perennials such as heucheras are at their best at this time of the year with their vivid  colours and the delicate feathery seed-heads of perennial grasses  look dramatic covered in early morning dew, especially when spiders have been busy weaving their webs.  

With some carefully selected plants you can create seasonal interest in the garden.  Our favourite autumn trees, shrubs and perennials are listed below and now is an ideal time to plant these while the soil is still warm.  Spring flowering bulbs can also be planted for late winter/early spring colour to take you through the seasons.
