Shop nowAnnual flowers are the quickest route to a garden full of colour — sown, grown and flowering all in one season. They're the backbone of any cutting patch and pollinator border, gathering the easiest and most generous flowers from across our flower seed range. New to flowers? Our flower growing guide covers the basics.
Most annuals are sown in spring — the calendar shows when.
For non-stop colour, sow cosmos, zinnias, marigolds and cheerful sunflowers; for the vase, fill our cut-flower range; for wildlife, our pollinator flowers. Hardy annuals can even be sown in autumn for earlier, bigger plants.
Hardy annuals, like cornflowers and poppies, shrug off cold and can be sown direct; half-hardy annuals, like cosmos and zinnias, need warmth and are best started under cover, then planted out after frost. For colour that returns year after year, see our perennial flowers.

What is an annual flower?
One that grows, flowers and sets seed all in a single season, then dies.
What's the difference between hardy and half-hardy annuals?
Hardy annuals tolerate cold and can be sown direct; half-hardy ones need warmth and are best started under cover.
Which annuals are easiest?
Cosmos, zinnias, marigolds, sunflowers, cornflowers and nasturtiums are all foolproof.
When do I sow them?
Mostly in spring, though hardy annuals can be sown in autumn for bigger, earlier plants.
Do annuals come back?
No — sow them fresh each year, or grow perennials for colour that returns.
