Learn how to sow seeds and fill your garden with a feast of flowers throughout the year
Add hardy annuals such as cornflowers and poppies into your garden for quick and vibrant colour. They are easy to sow directly into the soil, inexpensive, and provide you with colour the same year if sown in spring, or the following year if sown in autumn.
Hardy annuals are great space-fillers among shrubs or look great in their own right. You can even consider growing them in containers.
A hardy annual is one you can sow outdoors in the UK, which germinates from seed, grows, flowers, disperses its seeds and dies in one growing season. (All in the same year if sown in spring, or from one autumn to the next).
There are myriad hardy annuals which you can peruse in garden catalogues and nurseries. Here is a list of favourites to choose from:
