Our Top Choices For Blue Flowering Perennials

The colour blue is a relative rarity in horticulture. Its complementary colour combination with greens, plus elegant contrast with whites make blue flowering perennials one of the most popular choices for a single or dual colour palette for garden designers. There is something about the connection with the blue sky and the surrounding myriad of greens in foliage that make blue flowers coveted, sought after and desired.

From the palest sky blues , through French Navy and shades of purple blue. This most regal of colours is one of our most popular requests by customers choosing perennials for the garden border. Here we reveal a few of our own favourites, as a source of inspiration, for choosing blue flowering perennials for your own garden…

Agapanthus – African Lily

Agapanthus Africanus Blue and Agapanthus Blue Storm
