We've picked our favourite purple-flowered perennials, shrubs and climbers to grow.

For a striking pot or border display, try combining purple blooms with the acid greens of Alchemilla mollis, or euphorbias like Euphorbia amygdaloides var. robbiae. Red poppies and orange kniphofias would also work well here.

For a more classic look, combine different shades of purple flowers with pink- and white-flowered plants.

Another benefit of growing purple-flowered plants is that they’re highly attractive to pollinators, with some showing an innate preference for purple flowers.
