Flower seeds to sow in August

We pick some of our favourite flowers to sow in August, including blooms for wildlife.

With late-summer’s warmth on your side, you can get plenty of flower seeds off to a flying start by sowing in August.


It’s also a good time to take note of any bare gaps in beds and borders. Many seeds can be directly sown in these areas now, ensuring glorious colour next year. Ideas to consider include a mini wildflower meadow, or a bed of hardy annuals.

Check out five flower seeds to sow in August, below.
