Clematis viticella Etoile Violette

Plants with purple flowers

Check out some of the best purple-flowered perennials, shrubs and climbers to grow.

Purple-flowered plants work well in most colour schemes, pairing just as effectively with whites and pastels as they do with hot reds and oranges.


For a striking pot or border, 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.
