20 of the best plants for autumn flowers

20 plants for autumn flowers

Keep your garden full of colour through autumn with a selection of late-flowering perennials, bulbs and shrubs. Some of the most popular plants for late colour include asters, sedums and Japanese anemones, which are at their peak as summer turns to autumn. But, if you have a small garden and can’t fit in extra plants for a new season, look for long-flowering perennials and shrubs that will bring colour from July right through to October. Salvias and fuchsias will fill your garden with flowers in summer and keep going for weeks on end.

For an instant colour boost, plant borders and containers with flowering perennials or shrubs in September. Then get planning to add more interest next year. In spring, sow annuals such as cup and saucer vine and plant dahlia tubers, then in early summer plant autumn-flowering bulbs like nerines.

We’ve picked 20 plants to grow for autumn flowers, below.


1

Dahlias

Dahlia ‘American Dawn’

Most dahlias will keep on flowering until the first frosts, providing welcome late colour after summer perennials have died down. There’s a huge variety of flower shapes and shades to choose from, whether you’re looking for a subtle single-flowered variety or a showy cactus or pom pom dahlia. Sow from seed or plant tubers in the spring. You can also buy plants in flower. In cold areas, tubers will need to be lifted for the winter.
