Late-summer borders need some vibrant colours and lush foliage in the mix of planting to catch the glow of September sun. September is when many plants experience a final flourish before dying down for the rest of the season. Long-flowering, hard working plants are ideal so the colours last well into autumn.

These are our top recommended plants and flowers for border in September, chosen by head gardener Tom Brown (TB), head gardener Mat Reese (MR) and nurserywoman Fleur van Zonneveld (FvZ).

The best September flowers and plants

Fuchsia hatschbachii

This graceful fuchsia will make a wonderful, lush shrub for the garden. It has relatively large, glossy green, willow-like leaves and bushy, copper stems. Its hummingbird-pollinated flowers are slimmer than those of Fuchsia magellanica, but otherwise look similar. The flowers are produced on the tips of the current season’s growth.

Ideally, plant in a sheltered position and cut back hard in the spring to promote strong, arching shoots that will show off the flowers and foliage to their best throughout September and autumn. Feed periodically through the summer and treat for capsid bugs to ensure a good display of flowers in September and October. MR
