Why We Love It

‘Blue’ is cherished for its intense colour, which stands out beautifully in early summer planting schemes. Its tall stems and refined flower form make it perfect for adding vertical interest to borders, as well as for cutting to enjoy indoors.

Pair with whites and purples for a cool, elegant palette, or mix with warm-toned perennials like achillea, rudbeckia, or lupins for vibrant contrast. Hardy, reliable, and easy to grow, it will reward with years of repeat displays.
