10 annual climbers to grow from seed
Annual climbers are quick to grow and bear masses of flowers. We've picked 10 to grow.
Fast-growing annual climbers will quickly cover a trellis or obelisk and flower within weeks of sowing the seed. There’s a wide variety of annual climbers to choose from, from traditional sweet peas to more exotic Spanish flag and morning glory. While perfect for a container or border display in their own right, annual climbers are also useful for growing alongside more slow growing perennial climbers, filling the space that they will later occupy. Some annual climbers can be paired in the same display for a dramatic colour combination.
