Sweet peas are some of the the most versatile plants you can grow.
Train them up a trellis, pergola or obelisk, or support them with canes in large pots. They bring height and colour to borders and their scented blooms can be used as cut flowers.
Sweet peas dislike root disturbance so grow them in cardboard tubes, growing tubes or coir pots. This will enable you to plant them out in their containers without damaging the roots.
