The Best Flower Seeds to Sow in Autumn UK

Autumn is one of the most popular seasons to start growing flowers, second only to spring. By sowing from August to November, your flower seeds will have all winter to germinate and establish strong roots, ready to fill your garden with colour in spring and summer. 

Most of our flower seeds to sow in autumn (UK) can be sown inside in pots or trays before planting out after the last frost. If starting your seeds indoors, be sure to ‘harden off’ young plants by gradually acclimatising them to outdoor conditions.

We also offer a range of hardy annuals and perennials, from Californian poppies to ox-eye daisies. These cold-tolerant autumn sowing flower seeds can be sown directly outside in their flowering positions, where they’ll bloom spectacularly from spring onwards.
