As the days shorten and a crispness fills the air, there’s a part of us that wants to hold onto the vibrant warmth of summer. We cling to the last long evenings and the memory of sun-drenched days.
We believe the most beautiful gardens are the ones that keep giving, extending the season of blooms and bright foliage long into the autumn. This isn’t about the traditional fiery reds and oranges of autumn foliage, but about plants that hold onto their spectacular colour, providing a continuous display that bridges the gap between seasons. From bold, late-flowering hydrangeas to evergreens and stunning grasses, here is a selection of our favourite plants for extending colour in your garden well into autumn.
