If you've already started thinking about where to buy seeds online ready for next year, you're not alone. September is the month when we can really sit back and take stock of what flowered well this summer and what didn't, meaning you can start making plans for what to grow next year. It's also the perfect time to sow some seeds this month to ensure you get early spring flowers –  think ammi, larkspur, corncockle, antirrhinum, astrantia and Nigella, to name but a few. 

We've rounded up five of our favourites places to buy seeds online below, then make sure you check out our guide to the best online garden centres for more great places to stock up on seeds and get ahead with your 2021 garden plans.

Nicola Bird founded The Floral Project after realising that she could grow her own beautiful blooms in her back garden instead of buying cut flowers that have travelled halfway around the world. To create a community aspect under her philosophy of ‘Giving to Grow’, Nicola offers hand-picked seeds that she uses in her garden so you can grow alongside her. You can buy monthly flower kits as and when you want to sow, or join The Flower Club which is a monthly subscription service where you get the kit sent out automatically for a lower price. Once you've received your kit you will get a newsletter with instructions on how and when to sow so you can do it at the same time as the rest of The Floral Project community.
